| 摘 要： | 松藻煤矿井下＋335大巷C6岩溶裂隙出水点,由于接受地表汇水洼地水源的补给,最大涌水量达3 500m3/h,对矿井安全构成极大威胁.通过物探、巷探、施工截流巷等勘查方案揭露了C6＇岩溶裂隙通道,经过高压帷幕注浆阻断下渗通道等治理措施,排除了困扰该矿20多年的水害威胁,为煤矿类似水害的治理积累了宝贵经验.

| Abstract: | The karstic fracture water C6 exit point in underground +335m main roadway of Songzao coalmine,because of it takes in recharging from surface catch-pit,so the maximum inflow of 3500m3/h from the point composed huge threaten to mine safety.Through exploration measures of geophysical prospecting,tunneling prospecting and cutoff tunneling revealed C6 karstic fracture water channel.By the use of high-pressure grouted curtain to let off infiltration channel and other harnessing measures,to get rid of water flooding threaten which persecuted the mine for more than twenty years.It builds up valuable experiences for water flooding harnessing in similar conditioned coalmines. |
