Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to mining production field especially relates to a gas drainage drilling drill way dust fall system in pit.
[ background of the invention ]
Gas has become the largest source of danger in mines, and coal bed gas pre-extraction is one of effective means for eliminating the source of danger. In order to realize gas extraction, drilling and pre-extraction must be carried out on the coal seam of the excavation activity space. The drilling machine is a main device for underground extraction and drilling construction, and a plurality of problems are found in the drilling construction process at present, wherein the problem that the dust yield is large in the drilling construction process is more prominent. Because the coal quality is soft, the wind power is mainly adopted for powder discharge in the gas extraction and drilling construction of the mine, and a large amount of coal dust generated in the construction process brings serious damage and hidden danger to the health of workers and the safe operation of equipment of a mine; in the past, orifice spraying, a water purification curtain and a dust suppression net are adopted, but the dust amount discharged by drilling can only be reduced to about 20-30% of the actual dust amount, and the orifice spraying does not play a dust suppression role in the dust suppression process due to the atomization effect, but flows into a roadway to bring new hidden troubles to production and operation, and the installation process is complicated, time-consuming and labor-consuming and cannot achieve the expected effect. A lot of unnecessary energy and cost are wasted, and the labor and the material are wasted for normal production, so that the working efficiency is seriously influenced.

[ detailed description ] embodiments
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a gas drainage drilling drill way dust fall system in pit, as shown in figure 1, include:
the dust collector 1 is a container without a cover, one side of the dust collector is horizontally provided with a through hole 2 and is attached to a front holder of a drilling machine, the other side of the dust collector is provided with a dust suction port 7 and is attached to a coal wall, a drill bit penetrates through the coal wall to drill a hole, and the dust collector 1 is used for collecting dust generated in the process of drilling the hole; one side of the dust collector is attached to the front holder of the drilling machine and is used for a drill bit of the drilling machine to pass through, the dust suction port 7 on the other side is attached to the coal wall to seal the periphery of the drilled hole, the bottom opening of the dust collector is used for discharging blocky drilling slag, the side opening of the dust collector is communicated with the axial flow fan 3, the dust collector 1 is made of iron and is a cylinder without a cover, the bottom of the dust collector is attached to the front holder of the drilling machine, the dust suction port 7 on the top of the dust collector is attached to.
A pneumatic axial fan 3, axial fan 3 passes through pipeline and dust collector 1 intercommunication, starts the fan and produces the negative pressure, and in order to guarantee the security, the fan adopts high-pressure gas to be power, and is simple and convenient, has avoidd the limitation that live equipment used.
