水文地质条件复杂区域回采工作面综合防治水技术应用

Application of Integrated Water Control Technology in Stope Face with Complex Hydrogeological Conditions

郑煤集团超化煤矿21001工作面回采前采用物探、化探、钻探多种手段对工作面进行超前勘测。根据工作面超前勘测成果,充分掌握含水层的发育以及老空水分布情况,分析评价该工作面地质及水文地质情况,计算工作面涌水量,以此为依据选择合理有效水害综合治理措施进行水害治理,确保工作面安全生产。

Geophysical prospecting,geochemical prospecting and drilling are used to survey the 21001 working face of Chaohua Coal Mine of Zhengzhou Coal Group.According to the advanced survey results of the working face,fully grasp the development of aquifer and the distribution of old empty water,analyze and evaluate the geological and hydrogeological conditions of the working face,calculate the water inflow of the working face,and select reasonable and effective comprehensive measures for water hazard control on the basis of this,so as to ensure the safe production of the working face.
