复杂条件下不规则块段综采面调斜延长技术

摘要

结合吉林省珲春矿业集团八连城煤矿现场工程实践，针对11907不规则工作面遇到的问题，提出了工作面的具体调采及延长方案，设计了机尾续架工艺，理论分析了工作面延长期间续架间距、工作面调采比例，制定了工作面延长续架原则、调采原则。现场生产实践证明，11907不规则综采面调斜延长技术保证了工作面安全持续开采，取得了不错的应用效果。%Adjustment mining and prolonging mining face projection was put forward and support -adding technique was designed for solving problem of 11907 abnormal mining face , Baliancheng Colliery of Huichun Mining Group .Support gap and adjustment mining proportion in mining face prolonging period was analyzed by theory .Support-adding and adjustment mining principle was formula-ted.Practice proved that the technology ensured safe and sustainable mining and obtained good effect .
