西陈庄矿3401工作面X11陷落柱导水性评价

西陈庄矿3401工作面在回采过程中揭露了陷落柱X11，为查明陷落柱的富水以及导水情况，对3401工作面进行的井下瞬变电磁探测的基础上，利用瞬变电磁法对3401工作面煤层及顶、底板进行物探探测，同时设计钻场，对陷落柱上部积水区、陷落柱内部、陷落柱底部奥灰水进行钻探验证，从而重新划定了陷落柱的边界，并对其富水性以及导水性进行了进一步的验证，为后期切眼的合理布置、工作面临时水仓排水能力的设定提供科学指导生产，确保工作面安全回采。

Evaluation of water conductivity of X11 collapse column on 3401 working face of Xichenzhuang Mine

It was necessary to expose the collapse column X11 in the mining process in 3401 working face of the Xichenzhuang Mine.In order to find out the watery and transmissibility of the subsided column，by using transient electromagnetic method to detect roof and floor of 3401 working face，and at the same time to design drilling field to verify the water conduction condition of the upper water accumulation area，the subsided column and the bottom of the collapse column.So the boundary of the collapse column was redefined and its water-rich and water-conductive properties were further verified.In order to arrange the incision more reasonably in the later period，to set up the temporary water tank of the working face，to provide scientific guidance for production，and to ensure the safe mining of the working face.
