| 摘 要： | 2007年开矿初期，在9#煤巷道掘进中发生多次冒顶突水事故，突水量可达4000～7200m3/d，给建井施工带来很大困难。根据井工三矿水文地质勘查、地面物探及地面疏排成果，结合矿井所处的地理位置，分析认为，矿井充水水源主要为4#、9#煤顶板砂岩裂隙水，充水途径主要是大沙沟隐伏露头导水通道，指出井田西北部大沙沟对煤矿安全开采的危害性较大，提出了修建排洪渠向下游引流的治理措施。结果表明，大沙沟治理后，井田内地下水的总补给量减少了83%，且将有1.92km2的煤炭储量获得解放，井田外也将有1.52km2的煤炭储量获得解放。并提出继续加强地面强排、井下探放水和地面变形恢复治理的建议。

| Abstract: | During the 2007 mining initial stage, many times of roof-fall water bursting accidents happened in No.9 coal roadway with outflow rate can be 4 000～7 200m3/d as high, brought a lot of difficulties in mine construction. Analysis based on underground coalmine No.3 hydrogeological exploration, surface geophysical prospecting and surface drainage data, combined with geographic situation of the coalmine, considered that the main water filling sources have coal Nos.4 and 9 roof sandstone fissure water, water filling path is mainly Dashagou River buried outcrop water-conducting channels;pointed out that the Dashagou River in northwestern part of the minefield has threatened coal mining safety largely. Thus, governess measures of drainage ditch construction to divert water to lower reaches put forward. The result has shown that after the Dashagou River governess, total recharge of groundwater to the minefield has been reduced 83%, coal reserves in 1.92km2 in minefield have been released and 1.52km2 outside the minefield as well. Suggestions to keep up sur-face strong drainage strengthening, underground water exploring and discharging and ground deformation recovery and harnessing put forward. |
