They should be taken as needed. The pipe box should be locked after taking them. The detonator leg wire should not be shortened in advance. The leg wire should be stripped with explosion-proof stripping pliers. It is forbidden to bite or pull with your teeth. The leg wire must be short-circuited after being cut. 6.1.3.4 Before making explosive packs, the gun line should be checked first to confirm that it is good and has sufficient length. One end should be short-circuited and the other end should be connected to the detonator.
6.1.3.5 After the explosive package is made, the gun line should be wrapped around the explosive package and tied. If the explosive package is composed of multiple columns, the detonating column should be installed last. 6.1.3.6 The prepared explosive package should be equipped with an anti-floating device or other anti-floating measures should be taken. Do not drag the explosive package in the air or on the ground. 6.1.3.7 It is prohibited to pack and store two or more explosive packages at the same shooting point at the same time. Multiple combinations should be packed and put down one by one. 6.1.3.8 When the drilling rig has not evacuated the well site, the explosive package should be temporarily placed 15m away from the well site and guarded by a special person to prevent vehicles from running over it. 6.1.4 The explosive package is lowered into the well
6.1.4.1 When lowering the explosive package, the gun line should avoid knotting and be moderately tight. 6.1.4.2 When using explosives placement tools, use stable pressure, do not use strong impact or vibration, and do not use drill rods or the power of drilling rigs to force the explosives. After placing the explosives, lift the gun line gently to check whether the explosives float. After the pit blasting, the pit must be filled with soil. It is forbidden to fill the pit with stones or hard soil. Someone must be on guard at all times. 6.1.4.3 If the explosive package is stuck, it must not be smashed or lifted, otherwise it will be detonated as a bomb. 6.1.5 Triggering
6.1.5.1 Before firing, the blaster must check whether there are houses, bridges, levees, power transmission and communication lines, oil and gas pipelines and other buildings and structures in the danger zone around the pit.
