新型高分子材料在破碎顶板回采巷道中的应用

New high molecular material applied in extraction heading having cataclastic upper plate

近年来,随着淮南矿区煤矿开采深度的增加,矿井地质条件日趋复杂,冒顶、水患等问题不断发生,严重影响安全高效生产。丁集煤矿应用新型高分子材料,对首采面回风顺槽的冒顶区进行加固、堵水、充填,支护效果显著,为同类条件下的巷道施工提供了借鉴。

Along with deepening of coal exploitation in coal mines in Huainan Region, the geological conditions become complicated day by day. Accidents such as roof collapse, water leakage or inrush occur often that influence severely the safety of mining operation. In Dingji Coal Mine, the new high molecular material is used to stop water leakage, fill and strengthen the collapse-danger section of upper plate of extraction heading thus achieving good supporting performance. The experience can be taken for reference when similar headings are constructed.
