通过对我国各地区坚硬难冒顶板统计研究,以各地煤矿实践经验为依据,提出了目前我国坚硬难冒顶板大面积垮落的集中控制方法,指出现阶段我国对坚硬难冒顶板大面积,垮落的主要方法是:提前爆落顶板控制法、充填式顶板控制法、煤柱式控制顶板法。并对各控制方法的工艺及优缺点进行了比较,对相似条件下坚硬难冒顶板大面积垮落的控制具有理论指导和参考价值。
通過對我國各地區堅硬難冒頂闆統計研究,以各地煤礦實踐經驗為依據,提齣瞭目前我國堅硬難冒頂闆大麵積垮落的集中控製方法,指齣現階段我國對堅硬難冒頂闆大麵積,垮落的主要方法是:提前爆落頂闆控製法、充填式頂闆控製法、煤柱式控製頂闆法。併對各控製方法的工藝及優缺點進行瞭比較,對相似條件下堅硬難冒頂闆大麵積垮落的控製具有理論指導和參攷價值。

Hard and difficult falling roof in various areas of our country are statistical researched,the practical experience in various coal mines are as evidence,the centralized control methods that large area caving of hard and difficult falling roof in our country at present are put forward.The main methods of large area caving of hard and diffi-cult falling roof are pointed out,such as blasting roof in advance control method,filling type roof control method,coal pillar type roof control method,and the technology and advantages and disadvantages of the control methods are com-pared.It has a theoretical guidance and reference value for control hard and difficult falling roof large area caving un-der similar condition.
