When connecting the drill pipe, aim at the thread opening to avoid external inclination and water leakage. When unloading the drill pipe, the pipe wrench should be strictly prevented from clamping the cemented carbide piece and flattening the drill bit. When loading drill pipes, they must be installed one by one.
2. Safety technical measures for platform operators
(1) Drilling workers should dress neatly, and the corners, cuffs and trouser legs must be tied tightly.
(2) Pay attention to the opening and closing of the switch. Keep your hands on the button and your eyes on the rig. Observe and obey the driver's orders at any time. The opening and closing of the switch should be accurate, timely and rapid.
(3) It is forbidden to directly brake the mechanical running part with hands and feet. It is forbidden to place other tools on the protective cover of drilling rig, water pump and motor.
Technical measures in the process of construction
1, strictly according to the design and construction, shall not arbitrarily change the design. Any change shall be approved by Party A's designers and relevant leaders.
2. Technicians should guide, identify and collect data in strict accordance with the design requirements, ensure the core recovery rate and collect all the obtained technical parameters.
3. Party A shall supervise the construction process and results. At the same time, be responsible for coordinating related matters that need to be handled by Party A during the negotiation.
4. The construction personnel consciously abide by the rules and regulations of the mine, and it is strictly prohibited to conduct illegal operations, illegal command and "three violations" in violation of operating procedures. If there is any violation, it will be handled according to the relevant regulations of the mine.
5, well personnel must be familiar with the route to avoid disasters, waterproof, gas, coal dust explosion route to avoid disasters.
6, well personnel must wear overalls, rubber boots, wearing a miner's lamp, self-rescuer, according to the prescribed route, well.
7. Pay attention to driving safety when going down the well, pay attention to watching and listening to driving signals, and achieve "no one drives up and down the mountain, and pedestrians don't drive".
8. The monitor is a part-time on-site safety officer, who is responsible for leading the class personnel to go up and down the well. After running in the well, be responsible for checking the support of the machine nest, equipment integrity and borehole conditions to ensure safe construction and unsafe construction.
9, the construction site to install special telephone, in order to report the accident to the mine in time.
10, ensure the ventilation, water supply and power supply of the construction site, and notify the construction personnel in time if there is no ventilation or construction, so as to take timely measures to prevent accidents in the hole.
1 1. Ensure that the electrical equipment is in good condition and explosion-proof. Cable connection should use special junction box for mine, and there should be no "chicken feet" and "sheep tail".
12, strengthen the management of gas detection, regularly detect the gas concentration on the construction site, evacuate personnel in time when the gas exceeds the limit, and report to the mine operation department. The automatic gas detection alarm must be hung within 5 meters of orifice return air measurement and kept in good condition.
13. Before drilling, clean ditches and sump pits to ensure smooth drainage. If the construction site is lower than the main ditch and sump, a large enough temporary sump should be built on the construction site and a water pump with large displacement should be installed.
14. Before blasting, tunneling or other construction that may endanger the safety of drilling construction personnel, mine construction personnel shall notify the drilling personnel to evacuate in time.
15. The cement used for pipeline cementing has no less than 525#, no deterioration or caking, and the cement slurry concentration is no less than 1: 0.6 (cement: water).
16. After the orifice pipe is fixed, sweep the hole to the specified depth, and pressure test must be conducted. The test pressure shall not be lower than 10MPa, and Party A's personnel shall be present during the pressure test. After passing the pressure test, it shall be signed by both parties.
17. For drilling holes that need to pass through aquifer (lime fly ash), orifice pipe gate valves and "blowout preventer" devices should be installed in advance, and all devices must be flexible and reliable.
18, the back pressure device is to prevent the drill pipe from being ejected by water pressure when tripping in, damaging the equipment or causing personal injury, so the back pressure device must be installed.
19, strict succession system, on-site succession, off-duty succession, hole situation, footage and horizon of this class.
20, technical problems existing in the construction process timely report to the site technical personnel, in order to solve in time.
2 1. When the water inflow and water pressure in the hole suddenly increase and the phenomenon of top drilling occurs, it is not allowed to lift or continue drilling at will. Need to report to the on-site technical personnel, and report to the mine dispatching room.
22, in the process of construction, normal drilling, in addition to the operating personnel, other personnel shall not be close to the mechanical operation parts, so as to avoid injury accidents.
23, normal construction or drilling, in addition to the operator shall not be close to the orifice, to prevent the hole water, gangue jet cuts.
24, underground personnel shall not take off their boots, hats, miner's lamps, self-rescuer, underground shall not sleep, shall not lie on your back, check the top and help at rest, to know whether to drive, whether there is construction nearby, and sit down and rest after confirming safety.
25, underground shall not walk, when no one leads shall not be far away from the construction site, ventilation roadway or don't know whether ventilation roadway shall not enter. When walking in an alley, especially when carrying conductive tools, you must always pay attention to the traffic to prevent traffic accidents. At the same time, pay attention to the tools in your hand and don't touch the overhead line.
26. When loading and unloading drilling tools, hold tools and drill pipes firmly in your hands to prevent them from falling into the hole and causing accidents in the hole.
27, it is forbidden to fire, cigarettes into the underground. It is forbidden to drink and smoke underground.
