摘　　要：针对复合煤层回采工作面煤炭生产过程中爆破参数的合理选取问题，进行了一系列现场试验。深入探讨了复合煤层回采工作面“松动放炮”落煤的工艺问题。： To counter the reasonable selection of blast parameters in the process of coal production in a composite coal seam face, a series of on-the-spot tests were conducted. This paper goes further into the blast-winning technology of the composite coal seam face.
