摘要
对叙永煤矿开采过程中的沿空留巷技术进行了研究。该技术在叙永煤矿应用后实现了回收安全保护煤柱,提高了煤炭资源采出率,降低了矿井掘进率,有效缓解了采掘接续紧张的局面,为实现回采面Y型通风创造了条件,解决了回采工作面上隅角瓦斯积聚难题。
Coal mining technology of Xuyong Coal Mine are studied. After nearly five years of exploration, recycling security protection has realized, the recovery rate of coal resources and reducing coal pillar mine drivage rate,effectively relieving the tense situation of mining connection and creating conditions have improved for realizing of stopping face Y-type ventilation and solving the stopping work top corner gas accumulation problems.
