论文介绍了现代煤矿运行中瓦斯浓度的计算方法,也提供了保证煤矿安全生产所需要的对各个工作面和通风巷的通风量的控制方法。对煤矿的安全生产具有指导性意义。文章针对2006年全国大学生数学建模竞赛D题“煤矿瓦斯和煤尘的监测与控制”中三个安全问题,分别建立了三个模型:第一,模型Ⅰ用以判别煤矿是高瓦斯还是低瓦斯矿井。第二,模型Ⅱ通过函数拟合手段,并建立几何概率模型,用以求出某一确定煤矿的不安全程度。第三,建立了一个线性规化模型,实现了保证安全时各个通风巷的通风量控制。
This paper introduces the calculation method of gas concentration in the operation of modern coal mines, and also provides the control method for the ventilation volume of each face and ventilation lane required to ensure the safe production of coal mines. The safety of coal production has guiding significance. In this paper, for the three safety issues in the 2006 National Collegiate Mathematical Contest D, “Monitoring and Control of Coal Mine Methane and Coal Dust”, three models were established respectively. First, Model I is used to judge if the coal mine is of high gas or low gas Gas mine. Second, the model II through function fitting means, and the establishment of geometric probability model to determine a certain degree of unsafe coal mine. Thirdly, a linear regularization model has been set up to realize the ventilation control of each ventilation lane when the safety is ensured.
