摘要
本文提出顶板动态监报应包括回采工作面局部冒顶的监报及顶板来压的预报这两个方面的观点。初步给出了局部冒顶监报指标的确定方法;重点探索了采用回采工作面来压综合判断指标来预报顶板来压的可能性。文中所给的回采工作面局部冒顶的监报指标及顶板来压预报指标所采用的系数,基于现场统计资料,或现场经验的数学处理结果。
In this paper a new viewpoint has been presented that the roof behavior prediction should include both the local roof fall prediction and the roof weighting prediction. The method of determining the index for predicting local roof fall has been given, the possibility of using a comprehensive index for roof weighting prediction has been discussed in detail. All the coefficients used in this paper are derived from in situ statistic data and results of mathematicalprocessing.
