不规则采煤工作面回采技术研究与应用

Research and application of coal mining technology of complex structure irregular working face with high stress in the upper coal

白庄煤矿作为肥矿集团仅有的老区之一,经过多年的生产,遗留在上组煤的采区边界和临近的边角煤较多,为减少煤炭资源的浪费,结合白庄煤矿上组煤高应力煤柱实际情况,对白庄煤矿三层煤不规则工作面的回采技术及安全生产进行研究。

Bai Zhuang coal mine as only one of the old fat mining group, after many years of production, on the left in group of coal mining boundary and near the edge of coal is more, in order to reduce the waste of coal resources,combined with Bai Zhuang high stress on coal mine coal pillar actual situation, the dialogue of irregular three layers of coal mining working face in coal mine technology research and studies the safety in production.
