1 rig safety rules, before the jet grouting rig drilling rig into the room, which must be acceptance of the room and carefully check the specifications support cases, equipment room specifications meet the construction requirements, reliable support, cap tightly. 2, before the rig into the room, you must carefully check the engine room and roof support conditions and the situation near the roadway, roof overhang refuse to pick the next time with Changgan tools and real top pick, if roadway deformation, supporting material deterioration , shed legs broken and must be replaced in advance, to strengthen support. 3, the rig operator before operating the rig to rig to integrity and security checks, find faults or safety hazards promptly notify the maintenance man maintenance treatment. To rig maintenance man in charge of each working day to check the integrity of the rig, identify problems in time. 4, rig workers must be familiar with the business operations, certificates, prohibited the use of high-speed, in order to avoid some of the man-made catastrophes. 5, tools, accessories and other items should not be placed on the rig, 6, during construction, the driller must be certified, not free to leave the rig, construction workers must wear clothing line with national standards for protective clothing, must be neatly dressed and cuffs , skirts, trousers fastened to avoid clothes belt and other rotating parts involved in wounding. 7, when operating the rig roughnecks, you must stand before the operation panel, left hand on the stop button at the right hand operation, so that "Three Views", "two", "one-time" Jet rig manufacturers, namely watch operating handle vibration, pressure and feed speed footage, see pump pressure gauge and backwater situation Jet rig, see belts and faucet fittings situation; listen to the sound operation of the machine, listening to the sound hole vibration; abnormal timely stop drilling process.
