浅埋深薄基岩煤层过沟开采水害防治技术

摘要

针对红柳林煤矿煤层埋藏浅、基岩覆盖薄且矿区范围存在沟壑的回采地质条件，以15207工作面回采为例，结合矿区水文地质条件，分析预测了工作面过沟开采遇到的涌水量及水害程度，提出了浅埋深薄基岩综采工作面过沟开采水害防治的具体措施，为安全回采提供了有力保障。%According to the conditions of shallow buried, thin bedrock and existing ditches in Hongliulin Coal Mine, taking№15207 working face as example, combined with mine hydrogeological conditions, the water disasters were predicted and measures of water hazards prevention and control were proposed when fully mechanized mining face passing through the ditch.The research provides a powerful guarantee for safety mining.
