A gas slag collection and separation device for coal mine punching

Abstract

The invention discloses a gas and cinder collecting and separating device for coal mine punching and relates to gas and cinder separating devices. The device comprises a collecting box and a separating box, wherein a fixing device used for being fixed in a gas extraction hole is arranged on one side of the collecting box, a fluid channel communicated with the interior of the collecting box through a fluid inlet I formed in the collecting box is arranged inside the fixing device, an opening enabling a punching drill rod to pass through is formed in the other side, opposite to the fixing device, of the collecting box, the opening is opposite to the fluid channel, a fluid outlet is formed in the collecting box and is connected with a fluid inlet II formed in the separating box through a pipeline, the fluid inlet II is communicated with a separating chamber arranged in the separating box, a gas extraction port is formed in the upper portion of the separating chamber, and a cinder notch is formed in the lower portion of the separating chamber. The device can collect and separate mixed fluid containing gas, water, coal cinder and the like generated during punching, and therefore the purpose of preventing outburst of gas from orifices is realized.

Description

technical field [0001] The invention relates to an air slag separation device, in particular to an air slag collection and separation device for coal mine punching. Background technique [0002] As coal mining becomes more and more difficult, the problem of gas outburst is becoming more and more serious. In order to solve this problem, the most ideal method at this stage is to use punching technology. After the gas drainage hole is drilled, high-pressure water is injected to flush the inside of the coal seam into a cavity, which effectively increases the diameter of the drill hole, enhances the gas permeability of the coal seam, and is conducive to gas release. However, a large amount of gas, water and cinders will be produced during the punching process, and the gas, water, cinders, etc. are mixed together, which is not convenient for the collection and discharge of gas. Moreover, problems such as gas outburst and spray holes will also be encountered. In addition, the lar...
