Description

Technical Field

[0001] The invention relates to the technical field of mine slope confined water treatment, and in particular to a drilling device for a confined water layer on an open-pit mine slope. Background Art

[0002] When mining in an open-pit mine, a large pit needs to be dug downwards to dig out the mineral resources. During the mining process, the pressure generated by the collapse of the mine will cause the surrounding groundwater to flow into the well, thus forming underground pressurized water. Underground pressurized water poses a great safety hazard and economic loss to mining production, so the prevention and control of slope pressurized water is very important.

[0003] At present, the method for depressurizing pressurized water is to use drilling waterproofing, and traditional equipment only uses ordinary drilling equipment for drilling. During drilling, pressurized water will seep out of the borehole. At the same time, after the pressure is released, an independent machine is needed to fill the borehole with sealing slurry for sealing. During this period, the pressurized water will continue to overflow, affecting the solidification of the sealing slurry. In addition, traditional drilling equipment cannot adjust the drilling direction, and drilling in mine slopes often requires drilling in different directions to release the pressure and seal the pressurized water, which has poor applicability. Therefore, the present invention proposes a drilling device for open-pit mine slopes containing pressurized water layers to solve the problems existing in the prior art. Summary of the invention

The drilling device for open-pit mine slopes containing pressurized water layers can achieve drilling requirements at different angles by setting an articulated support arm in conjunction with multiple groups of oil cylinders, and can also adjust the drilling height. The adjustable range is greatly increased, and the applicability is improved, which solves the problems existing in traditional drilling equipment. At the same time, the drilling drive mechanism can immediately extract the pressurized water through the hollow drill rod and the through-connected rotating positioning head after drilling, so as to avoid overflow of pressurized water and cause excessive water in the hole affecting the subsequent injection of sealing slurry.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0019] With the rapid development of my country's economy, the development of energy industries such as coal has also shown a rapid growth trend. However, there are more and more problems caused by this, such as coal mine safety, mine drainage, mine environmental protection, etc. Especially for open-pit mines, due to the limitations of geological conditions, it is more common to have excessive underground pressurized water, which brings great safety and economic risks to the production of mines.

[0020] When mining in an open-pit mine, a large pit needs to be dug downwards to dig out the mineral resources. During the mining process, the pressure generated by the collapse of the mine will cause the surrounding groundwater to flow into the well, thus forming underground pressurized water.

[0021] Underground pressurized water has caused great safety hazards and economic losses to mining production, which are specifically manifested in the following aspects:

[0022] 1. Slope instability: The stability of the slope of an open-pit mine directly affects the safety and efficiency of mining; underground pressurized water can cause the slope to become soft and unstable, leading to accidents such as instability, landslides, and even collapses;

[0023] 2. Natural gas gushing out: During open-pit coal mining, the natural gas contained in the underground pressurized water will gush out along with the water. When the concentration of natural gas exceeds a certain value, an explosion will occur, posing a threat to personnel and equipment.

[0024] 3. Reservoir blocking: If there is too much underground pressurized water, it will cause accumulation in the reservoir. Long-term accumulation will have irreversible impacts on the surrounding environment and ecology.

[0025] The method of depressurizing pressurized water is to use drilling waterproofing, but traditional equipment only uses ordinary drilling structure. Pressurized water will seep out of the borehole during drilling. At the same time, after the pressure is released, independent machinery is needed to inject sealing slurry into it for sealing. During this period, pressurized water will continue to overflow, causing the construction site to be muddy, and the drilling direction cannot be adjusted, so equipment with different structures needs to be used.
