摘  要:为了解决煤矿采掘工作面瓦斯涌出及巷道风量不足的问题,文章优化了马尔科夫模型,预测了工作面瓦斯涌出量,相比传统模型,最高误差降低约15.4%,相对误差降低约4.56%。同时,针对各巷道风量情况,新建通风巷道,并调整通风机叶片角度,以弥补新建巷道的不足,使巷道各部分风量均达到预期设想,从而为煤矿安全开采提供保障。In order to solve the problem of gas emission in coal mining face and insufficient air volume in roadway,an optimized Markov model is established to predict the gas emission in the mining face,which reduces the maximum error by about 15.4%and the relative error by about 4.56%compared with the traditional model.At the same time,according to the air volume in each roadway,a new ventilation roadway is built,and the angle of the fan blade is adjusted to make up for the shortcomings of the new roadway,so that the air volume in each part of the roadway can reach the intended design,so as to provide guarantee for the safe mining of coal mines.
