本文依相似原理,把电模拟方法引入采场通风研究中,具体对义马矿务局常村矿1312无煤柱采场空气流场进行了电模拟研究实验。实践证明:电模拟方法与现场观测、物理模拟、数值分析相互补充更精确研究场问题是可能的。电模拟方法引入煤矿,对诸如通风问题的研究是有益的。 一、数学模型 常村矿无煤柱开采造成新老采空区连成一片,气体在巷道、工作面及采空区大面积
Based on the principle of similarity, this paper introduces the electrical simulation method into the study of stope ventilation, and conducts the electrical simulation research on the airflow field of 1312 coal-free pillar stope in Changcun Mine, Yima Mining Bureau. Practice has proved that it is possible to simulate the field problem by the method of electric simulation and the on-the-spot observation, physical simulation and numerical analysis. The introduction of electrical simulation methods into coal mines is beneficial for studies such as ventilation. First, the mathematical model Changcun non-coal pillar mining caused by new and old goaf into one, the gas in the roadway, face and goaf large area
