Each mine geological exploration project is inseparable from the system and process, safety issues have always been the topic of use throughout the construction site, geological drilling practitioners in the construction site, both to safety, strengthen safety and civilization construction, but also to ensure quality and quantity to complete the work, the collective system first, implementation to be in place, strong execution.

1. Before drilling, there must be a monitor or captain to enter the construction site for standardized work inspection, always knock on the top, check the stability of the rig, and whether the water pipe connection and rotation after the active drill pipe are intact and flexible. Implementation of spud preparation work in place. After the inspection is correct, all personnel withdraw to 0.8 meters away from the rotating part before drilling. Trainees and unlicensed personnel are not allowed to operate the drill rig and security guard, each rig is equipped with 2 people, the captain is responsible for starting up, the junior is responsible for loading and unloading the drill pipe, machine maintenance and other daily work.

2, the opening must be carried out according to the design requirements, the diameter and Angle of the opening hole should meet the requirements, and the depth of the opening hole should meet the requirements. After the drill starts, the first slow rotation, until the drill pipe drilling 20cm, can be high-speed drilling.

3, the drilling rig in the process of drilling, to observe the situation of the hole in time, abnormal or unexpected to stop immediately.

4. After the power is off, the gear must be adjusted in neutral (the middle state of the operating handle). When the drill pipe needs to be increased, the drill pipe must be stopped first, then the rotation must be stopped, and then the drill pipe must be added. When undrilling, rotate the powder on the side of the power head until the whole drill pipe is withdrawn, and then stop the rotation, the torsion unloading is completed, and the drill pipe can be removed. No one is allowed near the rig after drilling, and all staff must be fully dressed and not wear overcoats.

5, in the process of drilling, drilling faults occur, to use more rotation, less feed, the mud of the fault poured out. And report it to dispatch. Follow instructions. If there is a sucking phenomenon, the premise of the rig is stable, keep the rig idling, and contact the geological department in time to the site for monitoring.

6, under normal circumstances, the drill must go to multiple design targets, broken rod, drop rod, drill bit damage or burn, etc., to report scheduling, according to the situation to deal with the accident in the hole. It is prohibited to scrap or move without scheduling instructions.

7, all drilling workers, need to go through special training before the job, certificate, must carry out the "mine" safety "knowledge training, and pass the exam. Training on disassembly, assembly, transportation and roadway support is also required.

8. All personnel must be familiar with and master the underground disaster avoidance route. When an emergency occurs on the working face, the monitor and the captain should immediately direct the on-site staff to stop working, evacuate in an orderly manner, and report ventilation scheduling in time.

9, each construction of a drilling hole (including the scrap hole that does not meet the design requirements), to seal the hole in time, otherwise the next hole shall not be constructed.

10, when the test drilling problem must be immediately stopped for inspection, the tubing connection must be strictly connected according to the instruction manual, often check the oil level of the hydraulic oil in the tank, and timely supplement when the oil is lacking. Replace the anti-wear hydraulic oil every three months. When the hydraulic oil temperature is too high in the drilling process, it is necessary to check the cooling and stop the machine to check the cause.

11, the drilling site should be cleaned, the drill pipe, tools, etc. should be placed reasonably according to the established location, the rock powder discharged during the drilling process should be cleaned in time, and the drilling near the cleaning need to stop the machine and then clean up. If the column is found to be loose during drilling, it is necessary to stop the machine for tightening and straightening, and do not risk drilling operations.

12, all staff to strengthen personal self-protection awareness.
