Abstract

The invention discloses a gas inhibitor and a preparation method thereof. The preparation method comprises the following steps of: S1, calcium chloride is ground into powder by a grinding machine; S2, powdery calcium chloride is weighed in a second feeding pipe through a conveying auger and then put into a stirring box; S3, a thickening agent and a lubricating agent are input into the stirring box through a third pipeline; and S4, the thickening agent, the lubricating agent and the calcium chloride powder are fully stirred and mixed to obtain the gas inhibitor, then the gas inhibitor is discharged from a second discharging pipe of the stirring box, and the gas inhibitor is packaged for standby application. The gas inhibitor can be widely applied to fully mechanized coal mining faces, tunneling faces and the like of mining enterprises, inhibits gas desorption, guarantees safe production and has a bright application prospect.

Description

Technical field [0001] The present invention relates to the field of coal mine safety technology, in particular a gas inhibitor and its preparation system. Background technique [0002] Near region of high-intensity mining machines near the large quantity of sagging and unloading will have a normal 10 times, causing gas overrun. In addition, the corner of the coal mining surface is the air leakage collection area of ​​the mining area. The gas and cut coal unobstruction in the vacuum area, causing the gaburgic gain of the upper corner, causing major safety hazards. Therefore, conventional strengthening of ventilation, strengthening gas extracts and comprehensive strengthening of ventilation and gas extracts, have not yet reached a comprehensive effective gas over-governance application effect, and even low gas mines have to be managed by high gas region. Coal seam filling or spraying the water-liquid coal sample adsorption - the desorption characteristics will have a large change,...
