Kaifeng silent broken removal tool, Kaifeng rock expansive wholesale price 2 Methods carbatex SCA broken agent and Wire Saw joint mining blocks in there Wire Saw mines, can be used with SCA broken agent Jiaze joint mining blocks methods Wire Saw has many advantages, but its high cost, efficiency is slow, our general wire saw ergonomics as 1m 2 / h, the Italian fast Wire Saw is 2 ~ 6m 2 / h. If Wire Saw for horizontal cutting, crushing agents SCA with carbatex vertically cut the total cost will be reduced, improving the effectiveness of work. With this joint mining method, with beaded wire saw cutting horizontally, then vertically carbatex agents SCA broken cutting and cutting block, achieved significant benefits. About Wire Saw supporting equipment, performance, and mining methods, not described here, please refer to the relevant information. At present, some mines use Wire Saw horizontally after sawing, splitting wedge hit with perforated vertically separated, since playing wedge splitting losses (including drilling rigs and splitting surface is uneven) of about 20cm, so that blocks rate decreased by about 24%, if the switch carbatex SCA broken agent for vertical cutting, not only eliminates the need for labor, but also blocks the rate of increase. Tests showed: Stone shortage rate can be increased to over 20%. Some large foreign mining, using stone ore Wire Saw for vertical and horizontal cutting (stepped), then crushing agents SCA carbatex cutting block, this method can improve efficiency, reduce mining costs. For large and medium-sized mines, such joint mining method is a direction. Currently, the town of stone enterprises need to adapt to the development of the domestic the unit has developed a small, flexible, low-cost small beaded wire saw, it carbatex SCA broken agent compatible with the use, even more powerful, will make the entire stone mining industry greatly change, blocks production doubled, the quality has greatly improved. 3 Jiaze SCA broken agent and Black huoyao joint mining method is to use this method Jiaze SCA broken agent for vertical cutting, horizontal cutting carbatex SCA Presplit broken agent, then a small amount of black huoyao to lift large pieces of material from the bed, As shown in Figure 5. Horizontal spacer hole cutting surface mounted 入嘉泽 SCA broken agent plays the role of the pre-crack, into a small amount of black huoyao of 2 to 3 pores with carbatex SCA broken agent plugging holes, when the vertical cutting plane split, immediately fuse ignited, generate gas expander (sound small, muffled), the entire stone up, and to achieve separation purposes. Here to note three points: First, the distribution and the number of black huoyaobaopo hole, the second is the amount of each hole black huoyao appropriate general loading dose of 300 to 400 g / m 3. The purpose is not to hurt the stone can lift the stone. Black huoyao how much the amount, and rock mechanical properties, structure, segmentation volume, carbatex SCA broken agent Presplitting the degree, to go through testing to determine. This method for small material (10m 3 or less) effective for large pieces of material probably will hurt the stone, broken in the middle. ××× marble mine have used this method quite effective, it can reduce the difficulty out of the bed rock. Before 4 open trench method of cutting rock with Italian Wire Saw, from both sides of the first plane out of the mining trench, the purpose of the extraction of stone blocks into four free surface, which will help cut, generally with the 025 type drilling Cutting dual-use machine, this machine constituted by two tubular steel rods, these two steel rods linked together by the bracket and the casing, in which one is fixed, the role of the entire machine is fixed on the rock, the other is active, do the vertical and rotational movement of the drill pipe from the role. Ф204 or 1900mm ditching drill with dual rig, drilling a first step, the second step of the drill down, and put Ф200 or 190mm pulley is pressed into the hole with ordinary Wire Saw cutting, trench generally open in a V-type . Then, and then automatic pressure cutting machine rock. In this way out of the trench neat, not to hurt the stone, but the process more inefficient. Some of our multi-mine baopo open trench method, although fast, but hurt the stone, especially near the trench sides of the rock, by the vibrations, concussion depth of 2 ~ 3m, stone loss caused due to baopo opener up to 20%. In Italy it is forbidden to use zhayao marble mining in order to protect rock. Most mine-free country beaded wire saw, how do we propose two methods. 4.1 fully open with carbatex silent broken agent (SCA carbatex broken agent) in Trench Trench first two edge design line anti-hole drilling, pitch is generally 15 ~ 20cm, deep hole step height, and then to 60 ° tilt angle From 1 to 2 rows of outer dozen slant-hole, the resistance line of 40cm, the next resistance line is about 20cm, so conducive to swell out, easily broken, pitch in less than 35cm, 30cm row spacing in within, margins should be higher than row from the narrow 1 times in the side of the middle row spacing drill a hole, so that the edge of the rock crushing good effect. I, Ⅱ, Ⅲ broken rock layer by layer inside, after most of the rock excavation trench in the middle off the carbatex SCA finally broken two border agents poured into the trench were smooth holes in broken, so that both sides of the trench formation, ditch bottom with picks or artificial leveling, help the next mining operations, this method costs a little work, but can ensure not to hurt the stone mining platform, is a proven method. 4.2 Jiaze SCA broken agent with black huoyao joint open trench method open trench method for accelerating the construction schedule, this method can be considered. And the method is basically the same as the first in a row of playing both sides of the trench shock holes to eliminate and reduce concussion when baopo stone mining platforms, this step is very important. Then in the middle of trench drilled with a black huoyao the rock is broken into a working pit, the first bombing I, after the bombing Ⅱ, finally carbatex SCA broken agent, trimmed trench into the plane, shown in Figure 7. In the trench surface within 1 meter volley with carbatex agents SCA broken broken back into the black huoyao in its eyes, were loose baopo, so ditching drill. The advantage of this method is that ditching fast, the disadvantage is easy to hurt the stone. Therefore, we must more drilling, each hole into the black huoyao amount to be small, pitch 3 0 ~ 40mm, every hole fitted black huoyao amount 5 0 ~ 100g, sealing with Wong, Bentazone baopo to move, then manually or picks slag, must zhayao with ammonium nitrate. 5 Other 5.1 features are granite are hard, brittle, homogeneous, small cracks, joints have certain rules, for chunks of outdoor granite, along their joint surface drilling, put a small amount of black huoyao, put it into big break block into four large pieces of material volley, then cut into blocks segmented by carbatex SCA broken agent, which can greatly reduce costs. When using Jiaze SCA broken agent cutting block, it is appropriate Ф30 ~ 32mm drill hole, pitch control in 20 to 30 cm deep hole for the stone height of 80%, this relatively flat cutting surface. 5.2 Jade (gabbro class), generally in the sandwich generation in igneous rocks, varying thickness, generally 20 ~ 200cm, jade is a valuable decorative stone and carving stone, high value, such as mountain jade, famous Chinese and foreign, it's hardness f = 7 ~ 8, translucent, color magnificent. But jade mining is very difficult, first with zhayao tunnel excavation, find jade with traces of black huoyao then broken rock near, if jade with three free surface, you can use SCA broken agent carbatex cut to ensure jade into separate blocks, Especially advantageous for thin strip mining jade. For spin-off chunk of jade (2 ~ 3m 3), by cutting carbatex SCA broken agent most appropriate to reduce jade damaged, it is appropriate Ф30 ~ 32mm in diameter, pitch 20 ~ 25cm, deep hole cutting height of 90 %, this relatively flat cutting surface. 5.3 Jiaze SCA broken agents are generally not suitable for quarries, building stones because of low prices, and low carbatex SCA broken agent crushing efficiency, and high cost. However, from the village, factories, roads close to the quarry, in order to avoid the damage to lives and homes, available carbatex SCA broken agent Presplitting rock, and then black huoyao loose baopo, so fly rock control in 10m of inside. The specific method is: the volley surface formations within 1 ~ 2m, drilled 4 0 × 40cm plum eye, filling 入嘉泽 SCA broken agent, after the rock cracks, rocks back in the eye, into the black huoyao initiation, The rock crushing. Cloth eyes and black huoyao dosage should be determined according to the amount of baopo and flying rocks from the side. Joint This method of static pre-cracking agent Jiaze SCA split and black huoyao (or ammonium nitrate zhayao) dynamic baopo, the cost will increase, but demand safe or suitable quarry face. Some 5.4 blocks plastic blocks mined, its size and irregular shape, not up to standard requirements, large artificial trimming work. SCA broken agent available at this time Jiaze shaping, as shown, along the cutting line drilling, irrigation 入嘉泽 9 SCA broken agent, to make the surface smooth blocks, use a small aperture (Ф 30mm or less), pitch 20 ~ 25cm, hole depth 0.9H. Since cutting thin thickness, in order to save carbatex SCA broken dosage, 1: 0.38-0.45 large cement ratio Jiaze SCA broken agent mixed into the slurry poured into the hole, cracking time may be long, but to achieve the shaping effect.
