Five, complete the high-pressure pipeline, replace the gun drill, move or renovate the rock drill, clean the water tank, etc. , should be carried out after the relevant feng shui valve is closed. It is forbidden to blow away dust and stone chips directly with high-pressure air in the rubber hose. Six, blasting equipment before use should be in accordance with the requirements of the relevant provisions of the quality inspection. The length of lead wire used in each gun should be determined according to the combustion speed; The combustion rate should be measured in batches. The connection between the lead and the detonator shall be carried out in the processing room or the designated place according to the quantity required at that time; Detonator tongs must be used when connecting, and it is forbidden to bite with teeth. Seven, the initial charge must be made when charging, it is forbidden to put it on hold in advance. When making, it is forbidden to insert the detonator directly into the primary explosive charge. A small empty hole with a depth of 1.5 times the length of the detonator must be inserted into one end of the explosive charge with a wooden stick or bamboo drill rod with the same diameter as the detonator, and then a detonator with good lead wire is placed to close the orifice. Eight, to receive blasting materials, should be filled in by the person in charge of loading guns according to the required quantity at a time, and extracted from the warehouse after being examined and approved by the relevant person in charge.

When the gunner hears the signal that the detonator explodes, he must immediately stop shooting and enter the safe area. And report the shooting situation to the gunner team leader in detail. The lead length of signal detonator should be 0.8m shorter than the shortest ignition lead, but its total length should not be less than1m. Ten, the detonator used in blasting must pass the inspection explosion, electric detonator also need to check the resistance, rusty detonator is strictly prohibited. 1 1. When the electric detonator is used for initiation, after the conductor laying is completed, the total resistance of the circuit should be checked by a special blasting bridge that has passed the regular inspection to make it meet the requirements. After the gunshot, the handle of the blaster must be removed immediately, and then the wire must be removed. After the smoke dissipates, it can be inspected in the blasting area. The handle of blasting equipment should always be carried, used and kept by the blasting squad leader. Twelve, when there is lightning near the blasting area, or when the rain clouds are diffuse and lightning may suddenly occur, it is forbidden to use electric detonators to initiate; In areas with gas, it is forbidden to use ordinary detonators for initiation. Thirteen, blasting line must be separated from the charged lighting line or power cord. 14. No other blasting work is allowed within 300m of the blasting site.
