煤矿瓦斯综合治理最常用、最有效的技术手段就是施工穿层、顺层钻孔预抽煤层瓦斯。由于潘北矿地质条件复杂，不同煤岩层岩性差异较大、赋存状况变化大，操作不规范等原因，易导致施工的钻孔出现偏差，造成钻孔的有效控制范围与设计不一致，影响了钻孔预抽效果。因此，通过采用“回归校正反演”等方法，来确保措施钻孔的有效控制范围，提高消突及瓦斯治理效果。

The most commonly used and effective technology means of the comprehensive management of coal mine gas is drilling pre-drainage coal seam gas in wear layers and bedding construction. The geological conditions in Panbei Coal Mine are complex, the lithologic differences of different coal rock are large, the change of occurrence condition is big, the operation is not standard, etc. All of these lead to the borehole deviation of construction, result the deference between the effective control and design of the drilling, and affect the pre-drainage effect of drilling. So, using"regression correction inversion"can ensure the effective control range of drilling and improve the effect of sudden elimination and gas control.
