我国冶金和化工矿山一部分倾角为25～50°倾斜矿体开采曾用或拟用爆力运搬空场法。据了解,这种采矿法我国过去之所以未得到应有的使用和发展,原因之一是对爆力运搬的理论问题研究不够,从而对这种技术的实际意义认识不足。为此,笔者和一些同行认为有必要介绍一下苏联空场法中爆力运搬距离的计 China’s metallurgical and chemical mines part of the dip angle of 25 ~ 50 ° inclined ore mining used or intends to use explosive force to move empty field method. It is understood that one of the reasons why this mining law has not been properly used and developed in the past in our country is due to the fact that there is not enough theoretical study on the movement of the explosive force to understand the practical significance of this technology. To this end, the author and some colleagues think it is necessary to introduce the Soviet air field method of explosive force to move the distance meter
