1511(3)工作面提高回采上限研究与实践

1511(3) Face to Loose Water Aquifer Under The Narrow Heading Face of Pillar Mining

潘一矿采1511(3)工作面为松散含水层下缩小防水煤柱开采工作面,本文通过对防水煤柱留设的可行性论证及实际开采过程中应用"并行电法"探测"两带"发育规律的介绍,为相似条件下提高回采上限开采提供借鉴和帮助。

Panyi Mining 1511（3） Face to loose water aquifer under the narrow heading face of pillar mining.Based on the design of water barrier pillars feasibility and the actual mining process application＂parallel electrical method＂detecting＂two with＂introduction of development law,Under similar conditions for the exploitation of the upper extraction limit for reference and help.
