Should be strictly in accordance with the design requirements of the job blasthole location, direction, angle, depth drilling facilities. Blasthole drills after all, have to use a hair blow tube boreholes and water exchange or cotton waste, waste paper and other openings to be blocked in charge. 4. Mixing: When using carbatex SCA broken agent broken agent, generally water-cement ratio of 0.30 to 0.35, the bag (weight 5kg) broken agent, add water, 1.5 ~ 1.75kg. When mixing, the first quantitative broken agent who fall within the plastic container, and then slowly added to the gauging water, mechanical or manual mix into a homogeneous slurry having fluidity alternate. Requirements mix, mixing time is no more than 3min. Such as the use KE crusher agent, first with a graduated cylinder to take the required number of liquid (liquid 303) plus the amount of water needed, stir with a stick, to dissolve uniformly, and then the master agent (powder) and the required adjuvants were mixed uniformly. 5. In the vertical hole oblique hole charge, it should be good medicine stirred slurry funnel with a scoop and quickly loaded the hole, tamping stick with guns. Such as excessive doses, should be grouped at the same time charge, within 10min marinated drug pulp and fashion manhole. Within a horizontal hole charge, the drug loaded pulp and borehole diameter in relation to the plastic bag, and then one by one with a gun stick into the borehole. Charge length of hole depth of 90%. 6. When the drug slurry filled vertical borehole, it may not clogged. Available inclined hole and horizontal hydraulic cement mortar or cement ratio of 0.25, dry hard carbatex silent broken agent medicine syrup jam, but all applications gun stick pound dense. 7. Charge plug after lh, that is, to the removal of body water. Spring, summer, autumn cold water; winter insulation measures should be taken and poured warm water to accelerate the hydration reaction, increasing the cracks. After 24h, it can be removed. Fifth, the quality standards 1. Shi burst after burst surface should be more regularly appear at a predetermined position on design, easy to remove the broken body to achieve the desired purpose broken. 2. Shi casualties in the explosion did not occur on the adjacent building (structure) did not affect and damage. Sixth, security measures 1. Stirring charge must wear rubber gloves and masks. While stirring, intense or excessive heating as the reaction, should immediately stop the hole interior medicine. When filling boreholes, the operator should wear protective glasses. 2. After the charge, the field should be left hand care. Before cracks, are not allowed to look into the orifice, eye injuries occur in case the discharge phenomenon. During operation, such as the drug gets on your skin or eyes pulp, immediately wash with water to prevent corrosion burns. After work, they should wash their hands and face, to prevent alkaline irritate the skin. VII Construction Notes 1. According to the actual construction of the ambient temperature to choose the right demolition agent model can not be misused or freely interchangeable. 2. Broken shipping agent shall use constrained container to avoid water intrusion, ejection occurs, burst or appear sound. 3. Broken agent to be stored in a dry ventilated place to prevent moisture deterioration, without moisture, the shelf life of one year. Storing the number of a long time, first put to use, use after release. Deadline, damp or previous unused just unpacked demolition agent before use to check whether the failure. Check method is: use the right amount of demolition agent Jiaze SCA broken and water, according to the proportion of the deployment is completed into glass bottles, crushed under the SCA carbatex agent model equivalent temperature, after a certain period of time, who was bursting bottles effective, or can not use. 4. Broken agent with the distribution with the use, one should not mixing too much; the stirred slurry should be installed as soon as the gun to the hole, and should be run in 10min, for too long, will significantly reduce the fluidity and the crushing effect. Such as the loss of fluidity, can not continue mixing with water use. Not in the winter, do not mix with hot water. 5. Should be checked before loading boreholes boreholes wet and dry, absorbent drying of blast holes should be wetted with water hole wall, then loaded, so as not to absorb a lot of moisture in the slurry, hydration and reduce the impact crushing effect.
