【摘要】 淮南新庄孜煤矿C13煤层属于严重突出危险性煤层,采用超前排放孔措施严重影响了掘进工作面生产效率,通过采用水力挤出与巷帮边掘边抽相结合的综合防突技术,较好地消除了工作面的突出危险性,巷道掘进速度提高1倍以上,实现了煤巷安全快速掘进。更多还原

【Abstract】 Taking C₁₃ seam in Xinzhuangzi Mine of Huainan as an example,the paper introduced that the comprehensive outburst prevention and control technology with hydraulic pressing and the gas drainage operation the gateway excavation could well eliminate the outburst danger occurred in the working face in seams with potential outburst,and the roadway driving speed intreased more than 1 time.Therefore a safety rapid excavation of the seam gateway could be made.更多还原
