摘 要:由于青磁窑煤矿受采动影响会产生离层积水等现象,采用地面泄水钻孔防治离层技术,提前在可能产生离层水区域施工地面泄水钻孔,及时监测工作面水位情况,预警井下出水现象。通过在1307、1302工作面现场应用后,均未产生显著的离层积水。结果表明,采用该技术能够发挥一定的防治效果,保证工作面的安全。Due to the influence of mining in Qingciyao Mine, the phenomenon of water accumulation in separation layer would take place. The technology of preventing and controlling separation layer by surface drainage drilling hole was adopted. Namely, the surface drainage drilling hole was constructed in advance in the area where the separation layer water might be produced, and the water level of the working face was monitored in time to warn the phenomenon of underground water outflow. After the field application of No.1307 and 1302 faces, no significant separation layer water was produced.The results showed that this technology could play a certain prevention and control effect and ensure the safety of the working face.
