Abstract

The invention belongs to the field of coal mine gas extraction drilling coal slag cleaning, and relates to a hydraulic slotting and drilling coal slag conveying and separating device. The hydraulic slotting and drilling coal slag conveying and separating device is used for separating coal slag and gas in a drill hole in the drilling and slotting process of a drill rod. The hydraulic slotting and drilling coal slag conveying and separating device comprises a drilling slag collecting device, a coal slag collecting box, a coal slag conveying pump, a coal slag separator and an automatic control system, wherein the drilling slag collecting device, the coal slag collecting box, the coal slag conveying pump and the coal slag separator are sequentially connected through a slag slurry pipe, and the automatic control system is used for controlling the coal slag conveying pump and the coal slag separator to be started and stopped; the drilling slag collecting device is arranged on the outer side of the drill rod and the end of the drill hole in a sleeving manner; the drilling slag collecting device, the coal slag collecting box and the coal slag conveying pump are all connected to a main extraction pipe through a gas extraction pipe; and a stirring impeller is arranged in the coal slag collecting box. The device can achieve automatic starting and stopping, operation is easy and convenient, the coal slag cleaning work human input cost can be effectively reduced, and the work intensity of field personnel is relieved.

Description

technical field [0001] The invention belongs to the field of coal mine gas drainage drilling coal slag cleaning, and relates to a hydraulic slit drilling coal slag transmission and separation device Background technique [0002] The proportion of high gas outburst mines in my country's coal mines is relatively large, and the construction of gas drainage boreholes inside the coal seam is the main method of gas control. At present, most coal mine construction gas drainage boreholes generally use hydraulic drilling. With the continuous development of coal mine gas control technology and equipment, hydraulic pressure relief and permeability enhancement measures have become the main means of coal mine disaster prevention and control. The ultra-high pressure hydraulic slitting technology has the advantages of strong coal breaking capacity, controllable slitting effect, and significant drilling pressure relief effect, and has been successfully popularized and applied in major mini...
