摘要
为了保证野川煤层三采区过空巷施工安全,分析了三采区老空区积水特征,对三采区采取“探、放、排、截”综合探放技术,并采取布置密闭墙的方式进行堵水。通过实际应用效果来看,采取综放防治水技术成功避免了过空巷期间水害事故的发生,保证了煤矿井下采掘施工安全,取得了显著应用成效。
In order to ensure the safety of construction in the third mining area of the Yechuan coal seam,the characteristics of water accumulation in the old goaf of the third mining area were analyzed.A comprehensive exploration and drainage technology of"exploration,drainage,interception"was adopted for the third mining area,and a closed wall was arranged to block the water.From the practical application results,it can be seen that the adoption of comprehensive caving water prevention and control technology has successfully avoided the occurrence of water accidents during the passage of empty tunnels,ensured the safety of underground mining and construction in coal mines,and achieved significant application results.
