本文介绍了用散体力学方法导出的在倾斜中厚矿体条件下的放出形体、最终放矿残留角、顶部加侧部及端部的混入废石体积、矿石贫损、崩矿和放矿步距,以及回采巷道位置等的计算公式,建立了放矿数学力学模型;应用电算模拟法模拟生产实际过程,编制了无底柱分段崩落生产电算程序,在电子计算机上进行了计算,并将计算结果整理成适于工程应用的图表。
In this paper, we introduce the release body derived from the method of stratum mechanics under the conditions of moderately thick ore body, the final residual ore discharge angle, the mixed volume of waste rock on the top and side and end, the loss of ore, the collapse and ore drawing Step distance, and the location of mining roadway, the mathematical mechanics model of ore drawing is established. The actual process of production is simulated by computer simulation method, and the computer program of subsection-free subsidence caving is compiled and calculated on the computer , And organize the calculation result into a chart suitable for engineering application.
