摘要
对钻孔径向流量法计算煤层透气性系数公式组进行了修正和优化。利用理论推导和拟合曲线的方法,探讨了流量准数Y与参数A、B之间的关系,得出了对流量准数Y与参数A、B关系的表达方程式,解决了钻孔径向流量法中煤层透气性系数计算无法找到合适计算公式或存在两个互相矛盾计算公式的问题,简化了计算步骤。实例分析表明计算结果具有较高的精度。
The calculation formulas of the permeability coefficient using borehole radial flow method were amended and optimized. The relation between flow number Y and parameter A ,B was studied by using theoretical analysis and curve-fitting method,and the equation of the relation between flow number Y and parameter A ,B was obtained, then a suitable seam in radial drilling flow method was found and there are formula Of permeability coefficient of coal no existence of two mutually contradictory formula, the course of calculation has been simplified.The example analysis shows that the calculation results have high precision.
