研究了采空区区域内的平均化的风流分布特性,并根据滤流场的理论进行了减少采空区漏风量技术措施的计算机模拟,结果表明,减少漏风的幅度为1708%~2426%.模拟结果减少了现场试验环节、降低了工程费用,经六枝矿务局木岗煤矿2a多的工业性试验和实际应用,证明了计算机模拟结果的正确性.
Based on the theory of the flow field, the computer simulation of technical measures to reduce the air leakage in the goaf was carried out. The results show that the range of air leakage reduction is 1708% ~ 24 26%. The simulation results reduce the field test and reduce the project cost. The industrial experiment and practical application of more than 2a in Mukang Coal Mine of Liuzui Mining Bureau prove the correctness of the computer simulation results.
