Abstract

The invention provides a dust catching system and method for gas drainage drilling. The dust catching system comprises a drill rod, a drilling machine, a drill rod clamp, a gas pipe and a gas valve and further comprises a dust catching device for gas drainage drilling. The dust catching device for gas drainage drilling comprises a dust fall spray chamber, a positioning sleeve, a spray nozzle, a water pipe, a water valve and a slag discharging guide device. The front end of the dust fall spray chamber is fixedly connected with the positioning sleeve; the top end of the dust fall spray chamber is fixedly connected with the spray nozzle, the spray nozzle penetrates into the dust fall spray chamber, the spray nozzle is connected with the water pipe, and the water valve is installed on the water pipe; the lower end of the dust fall spray chamber is connected with the slag discharging guide device; the front end of the dust fall spray chamber and the rear end of the dust fall spray chamber are provided with a first sleeve hole an a second sleeve hole respectively, and the first sleeve hole and the second sleeve hole are coaxial with the positioning sleeve, and the diameter of the first sleeve hole is equal to the inner diameter of the positioning sleeve. The dust catching system and method are good in dust removal effect, low in water consumption and simple and convenient to operate.

Description

technical field [0001] The invention relates to a dust collection system and method, in particular to a dust collection system and method for gas drainage drilling. Background technique [0002] Gas drainage requires extensive drilling of coal seams. And the drilling operation produces a large amount of coal cinders to be blocked in the borehole, which has a strong impact on the operation progress and the quality of the borehole. For this reason, it is necessary to carry out slagging operations while drilling. At present, in order to solve the problem of slagging, coal mine enterprises generally adopt two methods, one is wet slagging method, and the other is dry slagging method. The latter has become the first choice of many coal mining enterprises because it does not need to consume a lot of water resources and will not affect the roadway excavation operation. However, there are many problems in the implementation of the dry slag removal method, which need to be solved b...
