| 摘 要： | 改善顶煤冒放性是综放开采急需解决的关键技术之一,顶煤冒放性与煤体裂隙发育程度有着很大的联系。工艺巷深孔爆破就是利用爆破产出裂隙,在不影响采煤机正常割煤、不会对支架造成威胁的情况下改善顶煤的冒放性。主要介绍了工艺巷深孔爆破参数的确定及其在现场的应用。

| Abstract: | Improving the roof caving of the top coal is one of the key techniques deeded urgently by the comprehensive mechanized mining.The roof caving of the top coal is connected greatly with the developing extent of the cracks of then coal bodies.The improvement of the roof caving of the top coal by using the deep-hole blasting in the technical tunnel utilizes the cracks caused by the blasting under the conditions of no influence on the normal operation of the coal cutter and no threat on the support.This paper mainly introduces the determination of the blasting parameters of the deep-hole blasting in the technical tunnel and its application in the mining face. |
