摘要
介绍七台河矿区在适宜的开采条件下,积极探索掘进矸石井下充填技术,研究出适宜七台河矿区大倾角薄煤层条件下矸石井下充填的新技术和新方法,并取得了较好的实践效果,为进一步实现矿井绿色开采做出大胆尝试。
Under the suitable condition,Qitaihe mining area probed the packing under surface technology by waste rock positively,has discovered the new technology and method which is suitable to high inclination-angle and thin seam of Qitaihe mining area,which has got better practise result.
