摘 要:针对成庄煤矿3#层四盘区大采高工作面瓦斯突出,对矿井安全生产构成严重威胁等问题,通过对按照不同孔径布置的普通顺层长钻孔的瓦斯预抽试验效果比较,确定了3#煤层普通长钻孔预抽方案,为瓦斯治理提供了有效措施,提高抽采效率。工作面瓦斯预抽效果达到预期目标。In response to the serious threat posed by gas outburst in the large mining height working face of the fourth panel area of the third layer of Chengzhuang Coal Mine to the safety production of the mine,a gas pre-extraction plan for ordinary long boreholes in the third layer was determined by comparing the gas pre-extraction test results of ordinary long boreholes arranged according to different aperture sizes.This provides effective measures for gas control and improves extraction efficiency.The gas pre-extraction effect of the working face has achieved the expected goal.
