控制软岩层巷道成型的实践

Practice on controlling the soft rock roadway forming

为了消除软岩石巷道在掘进过程中因顶板冒落而对巷道成型产生的影响,从巷道实际地质情况出发,大胆进行探索和改革,总结出一套通过调整爆破参数和支护方式的方法,来保证巷道成型质量,从而消除巷道顶板安全隐患,为煤矿安全生产提供了有利的保障。

In order to eliminate the impact on the tunnel shape because of the roof collapse in the tunneling process of the soft rock roadway, starting from the actual geological conditions of the tunnel, it makes bold exploration and innovation, sums up a set of methods through adjusting blasting parameters and support patterns to ensure the quality of tunnel shape, so as to eliminate the potential safety hazard of roadway roof, and to provide a favorable security for safety production of the coal mines.
