煤矿防治水已广泛应用注浆堵水技术。例如井筒注浆、堵截含水层的帷幕注浆、堵突水点等。尤其是当矿井发生特大涌水造成淹井,通常采用地面打钻注浆堵水来恢复被淹矿井,而快速堵水:有时甚至能够挽救矿井不致淹没、并且尽量减少由此造成的损失,因此快速堵水具有十分重要的意义。焦作矿区是大水矿区,矿井突水是经常发生的,从五十年代就开展地面打钻注浆堵突水点,以后几乎连年不断,据不完全统计,共堵突水点26处,堵水量达1308米~3/分,其中采取堵水复矿的井口有11个次,共堵水810米~3/分.从七十年代以来,矿务局建立了注浆专业队伍,配置注浆专用设备,技术逐步改进,堵一个突水点的周期缩短到2—3个月,正沿着快速、高效和省料的堵水方向迈
Coal mine prevention and control of water has been widely used grouting water blocking technology. For example, wellbore grouting, plugging the aquifer curtain grouting, water bursting point and so on. In particular, when flooding is caused by large gushing water in the mine, grouting water is usually used to recover the flooded mine shaft and water is quickly shut down: sometimes the mine can be rescued from flooding and the resulting loss can be minimized, Water blocking is of great importance. Jiaozuo mining area is a large water mining area, mine water inrush is a frequent occurrence, from the fifties on the ground to drill grouting water plugging water breakthrough point, after continuous year after year continuously, according to incomplete statistics, a total of 26 water plugging, plugging The water volume reaches 1308m ~ 3 / min, of which 11 wells are used for plugging water and the total water plugging is 810m ~ 3 / min. Since the 1970s, the Mines Bureau has established a grouting professional team with configuration notes Pulp special equipment, and gradually improve the technology, block a water inrush period is shortened to 2-3 months, is along the fast, efficient and save water in the direction of the step
