1,Human causes

geological drill pipeAnalysis of which the commander or operator did not strictly and seriously implement various operating procedures and various rules and regulations.

In the construction of such accidents are particularly common, mainly including the following aspects:

(1) Commanders do not act according to objective laws, do not implement regulations and various effective systems, command in violation of regulations, and cause accidents. If the drilling tool is squeezed or the drilling tool is turned over and buried in the hole, the drill head does not carefully analyze the cause of the accident, but directs the operator to do it rashly, tie the rope hard or forcibly start the vertical shaft of the drill to drill back, causing the drill pipe to twist off.

(2）geological drill pipeThe operating personnel on duty of the drilling rig do not seriously implement the post responsibility system, do not operate according to the operating regulations, or operate carelessly during operation. If the shift change is not very good account of the operation of the water pump and drilling rig, blind succession, once the water pump does not come, the drill will burn.

(3) Weak technical management during construction, no regular inspection, lack of predictability of daily safety work, and lack of effective technical measures in more complicated situations.

(4) Drilling rig operators have low technical quality, inaccurate operation and unskilled. In addition, the drilling tool gradation is not reasonable, but also easy to cause the hole accident.

2. Mechanical reasons

In-hole accidents caused by mechanical factors are mainlygeological drill pipeDrawworks for the rig. If the diesel engine and electric motor suddenly fail during operation, the drilling tool cannot be raised at the bottom of the hole, and the drilling tool is also clamped to be removed, causing an accident.

3. Objective situation

It is mainly due to unforeseen natural disasters, such as flash floods and river flooding in summer, which will inundate the construction site, or debris flow ransacking the site, which will make the drilling tools unable to move out of the hole, and the drilling tools will be buried due to silting and flooding, resulting in the scrapping of the drilling holes.; Encountered fire while working in the forest area, spreading to the construction site and causing losses; sudden power failure causes the drilling tool to stay in the hole for too long time, which may also cause the clamping accident.
