摘要
在"三软"巷道中采用综放开采时,由于巷道及煤层本身的松软,容易产生顺槽等的大变形,在实际生产过程中,需要研究松软煤层工作面的走向和侧向的支撑压力的分布,避开峰值压力,从而确定超前的支护距离和下个顺槽的位置,再通过数值模拟确定丰汇煤矿的支护方式,为此类矿井支护提供了经验。
In fully-mechanized mining in three-soft roadways, soft roadways and seams could cause big deformation of gateways. In the practical production, the direction of soft seam mining face and the distribution of sidewise supporting pressure should be studied to avoid peak pressure and to determine the supporting distance and the position of next gateway. By numerical simulation, the supporting methods for Fenghui Mine were determined, which could be useful for similar mines.
