摘要
龙家堡矿410工作面的采深已接近1 000 m,目前时常发生较为明显的动力现象。为了降低冲击地压事故发生的概率,该矿采取了煤层爆破卸压技术,但卸压的效果还需要检验。采用地震波CT技术对煤层爆破效果进行检验,对该矿以后的煤层爆破卸压具有积极的借鉴意义。
The mining depth of 410 working face in Longjiapu coal mine is close to 1 000 m. At present it often occurs more obvious dynamical phenomenon. In order to reduce the probability of rock burst accident,the coal seam blasting destressing technology is took,but the blasting effect test is needed. Seismic wave CT technology is adopted to test the blasting effect of coal seam. It has a positive significance for the coal subsequent coal seam blasting destressing.
