摘要
根据岱庄矿３２２１０回采面的具体情况，从理论上试算了微差控制爆破时炮眼的间距、水平角和装药量等。同时运用正交法设计了试验方案，并获得了最优爆破参数，取得显著的经济效益和社会效益。
Abstract On the basis of concret condition of 32210 coal face of Daizhuang Mine a calculation was tried theoretically for the interval between blastholes, horizontal angle and powdered charge in controlled millisecond blasting. Orthogonality method was adopted to make the trial plan and the optimum blasting parameters derived which have achieved obvious economic and social benefits.
