Problems solved by technology
With this method, the length of the drilled hole is short, the trajectory of the drilled hole is uncontrollable, and the underground conventional drilled hole can only be constructed after the mining roadway is formed. The effect of releasing water is not good, and it cannot fundamentally solve the problem of mine water damage

Embodiment Construction
[0016] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the mine water disaster control method includes the following steps:
[0018] S101: Select the location of the drilling site, arrange the location of the drilling holes on the working surface, and design the drilling trajectory. A drill site is where personnel and equipment are located during operations. The working face is where the drilled holes are opened. In practical application, the location of the drilling site is selected according to the mine geological conditions, water storage conditions, roadway development conditions, mine drainage conditions, mine safety conditions, etc., the location of the drilling holes is arranged and the drilling trajectory is designed.
[0019] Preferably, the position height of the drilling site is lower than that of the working face, and the distance betwee...

The invention provides a mine water disaster treatment method which comprises the following steps of selecting a position of a drilling site, arranging a position of a drill hole on a work face, designing a drill hole track, utilizing a drilling machine to enable a screw motor to be propelled into the drill hole, pouring high-pressure water into the screw motor which drives a drill bit to cut rocks, cutting the rocks, measuring an inclination angle and an azimuth angle of the drill bit at the same time, controlling the drilling direction of the drill bit according to measured data and the drill hole track, forming a water drainage channel after the drill bit reaches a water bearing bed, and draining water in the water bearing bed through the water drainage channel. As the screw motor is utilized for drilling the hole, effects of being deep in the drill hole, low in cost and long in water drainage time can be achieved. Simultaneously, the angles of the drill bit are measured while the hole is drilled, the hole-drilling direction of the drill bit is constantly adjusted, the long distance of drill hole shuttling in the water bearing bed is achieved, and good water drainage effect is achieved.
Description
technical field [0001] The invention relates to a mine water disaster control method. Background technique [0002] In recent years, with the acceleration of the mine mechanization process, the speed of mine mining has been accelerated, followed by increasingly serious safety problems, and mine water damage is one of the major hazards of mine mining. The original water drainage technology can no longer meet the existing needs. In the face of increasingly severe mine water hazards, the emergence of new technologies, new methods, and new processes has become an urgent need. [0003] At present, water disaster control mainly uses conventional drilling rigs to construct large-angle elevation drilling holes in the roof aquifer in underground roadways or stone gates to drain the roof water in advance. With this method, the length of the drilled hole is short, the trajectory of the drilled hole is uncontrollable, and the underground conventional drilled hole can only be constructe...
