坚硬难冒顶板大面积垮落控制方法

摘要

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。%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.
