坚硬底板薄煤层巷道快速掘进的研究

The Research and Application of the Rapid Driving of Thin Coal Seam in Hard Bottom Sheet

新驿煤矿随着矿井开采的不断延伸,地质条件越来越复杂,断层多、煤层薄,提高薄煤层巷道掘进效率是解决下一步矿井接续的关键因素。对现阶段掘进优化了支护设计、提高了装备水平、优化了工序组织等措施,实现了最佳爆破效果,提高了掘进速度,取得平均每月成巷300多米的效果。

With the continuous coal mining, geological condition in Xinyi Mine is becoming more and more complex, fault being more, coal seam being thin, so it is the key to solve the next step in the mine to improve the effciency of thin coal seam roadway drivage.To solve the problem, Xinyi Coal Mine optimized the supporting design, improved the level of the equipment, and optimizing the process organization, achieving the best blasting effect, improving the driving speed, achieving the effect of more than 300 metres per month into lane.
