针对成庄煤矿4308综放工作面的地质概况和开采条件,对该工作面进行煤层静压注水试验研究。通过合理的煤层钻孔设计和施工工艺,优化了煤层注水参数,降低了工作面回采时产生的粉尘量和瓦斯涌出量,对于防治煤尘事故的产生和瓦斯治理意义重大。
Aiming at the geology and mining conditions of 4308 fully mechanized coal caving face in Chengzhuang Coal Mine, experimental study on hydrostatic pressure water injection was carried out on this face. Through reasonable drilling design and construction technology of coal seam, the parameters of water injection in coal seam are optimized, and the amount of dust and gas emission when mining face is reduced, which is of great significance to the prevention and control of coal dust accidents and gas treatment.
