采用现场实测、理论分析和数值模拟相结合的方法，研究了某主含水层煤矿突水的主控因素及防治方案。在对小吉汉煤矿西矿主要含水层煤层进行揭示和分析的基础上，应用PHASE-2D模拟软件对不同影响因素下的矿井涌水量进行了分析。结果表明，煤层突水量随煤层厚度的增加呈幂函数关系增加，随煤层渗透系数的增加呈幂函数关系增加，随煤层埋深和水头压力的增加呈线性关系增加;利用SPSS软件进行非线性回归分析，得到了煤层突水影响因素的评价模型。通过在小吉汉煤矿的工程应用，得出了井田范围内的矿井突水危险性评价分区。为确保矿井安全高效生产，从巷道掘进和煤层开采两个方面研究了某主含水层煤层的煤矿水害防治措施。
In this paper, a combination of field measurement, theoretical analysis and numerical simulation were used to study the main control factors of coal mine water inrush in a main aquifer coal seam and its control scheme. On the basis of revealing and analyzing the coal seam as the main aquifer in western coal mine of Xiao Jihan coal mine, the simulation software of PHASE-2D was applied to analyze the water inflow under different influencing factors. The results showed that water inflow increases logarithmically with the coal seam thickness, increases as a power function with the permeability coefficient of the coal seam, and increases linearly with the coal seam burial depth and the head pressure; The evaluation model for the factors of coal seam water inrush was gained by using nonlinear regression analysis with SPSS. The mine water inrush risk evaluation partition within the scope of the mining field was obtained, through the engineering application in Xiao Jihan coal mine. To ensure the safe and efficient production of the mine, we studied the coal mine water disaster prevention and control measures of a main aquifer coal seam in aspects of roadway driving and coal seam mining.
