摘要
杨庄煤矿资源匮乏,提高矿井回收率是增加矿井服务年限的唯一途径,本文结合矿井多年来在生产实践中创新经验做法,综合运用分层开采控制采高技术、无煤柱开采技术、三角煤调采技术、两端头放顶煤技术、综合防灭火技术,达到提高了资源回收率,促进矿井可持续发展目的。
The resource of Yangzhuang coal mine is poor, improve the recovery rate is the only way to increase the length of service of coal mine.This thesis combining the innovation practice of coal mine for over years,comprehensive using the t^hnology of slicing method to control mining height,technology of coal mining without pillars,technology of adjusting triangle mining,technology of top coal caving and technology of comprehensive fire prevention and control to improve the recovery rate of resource to promote the the sustainable development of coal mine.
