Problems solved by technology

However, the downward piercing hole has the following disadvantages: 1. The construction of the downward piercing hole is difficult and the hole formation is poor; 2. It is difficult to seal the downward piercing hole, and it is easy to cause the dug hole to be blocked when sealing the hole; 3. , Most of the bottom of the downward piercing hole has accumulated water, and the accumulated water will submerge the retaining flower tubes arranged at the bottom of the downward piercing holes, so that the gas cannot enter the retaining flower tubes, and the gas cannot be pumped out
However, its overall design is relatively cumbersome. The patent needs to separate the water and air first, and there is also a risk of airflow blockage. The overall design cost is high, but the actual risk is relatively high. Therefore, it is necessary to pump air and water from the perspective optimize

The device comprise a frame, wherein a treatment chamber is arranged on the frame, a foundation support is externally arranged on the front side of the treatment chamber, a main support is arranged on the foundationsupport, a steering wheel is arranged at the bottom end of the main support, an operation frame is arranged on the steering wheel, the bottom end of the operation frame is provided with an extractionmechanism through a locking installation sleeve, a main body of the extraction mechanism is a tubular outer fixed frame, the tubular outer fixed frame is provided with a water pumping channel and a gas production channel, the gas production channel is provided with an air flow end, the air flow end is obliquely arranged at the outer wall position of the tubular outer fixed frame, and the air flowend is obliquely inclined upwards and forms an included angle of 90 degrees with a rotary earth drilling rack. According to the device, the integrated separation type treatment adopts an independent operation system, so that no interference exists between water pumping and air pumping.

Description

technical field [0001] The invention relates to the technical field of outburst elimination in coal mines, in particular to an outburst elimination device for underground mining and an operation method thereof. Background technique [0002] At present, in coal mine production enterprises, using downward piercing holes to eliminate outburst is one of the important means to prevent and control coal and gas outburst. However, the downward piercing hole has the following disadvantages: 1. The construction of the downward piercing hole is difficult and the hole formation is poor; 2. It is difficult to seal the downward piercing hole, and it is easy to cause the dug hole to be blocked when sealing the hole; 3. , Most of the bottoms of the downward perforations have accumulated water, and the accumulated water will submerge the retaining flower tubes arranged at the bottom of the downward perforating holes, so that gas cannot enter the retaining flower tubes, resulting in that the ...
