摘要
通过理论分析和实践,探索出应用留小煤柱沿空掘巷方式,解决了回采孤岛煤柱等应力集中区域的煤炭资源时,回采巷道布置的难题,提高了采掘巷道支护效果,为安全生产打下了坚实基础。
By the theoretical analysis and practice, the gateway driven along goal with preserving small pillars solves the problem of roadway distribution in the stress concentrated areas such as isolated island pillars. The roadway supporting is improved, which lays the firm foundation for safety production.
