“两软一硬”不稳定煤层综放工作面矿压规律研究

通过对云煤二矿综放工作面的矿压观测,探讨了"两软一硬"不稳定煤层综放工作面采场矿压显现规律,评价了其支架的适应性,为工作面顶板安全管理提供科学依据,对相似条件下放顶煤工作面的开采具有指导和借鉴意义。

Research on Laws of Strata Behaviors at Fully Mechanized Caving Coal Face in Two Soft and One Hard and Unstable Coal Seam

Based on the observation and analysis of mining pressure at the fully mechanized caving coal face in Yun-mei NO.2 Coal Mine,the paper discussed the characteristics of the strata behavior at the fully mechanized caving coal face in the two-soft and one-hard unstable coal seam,and evaluates the adaptability of its support,it will provide scientific evidences for safety management of the roof.It also gives guidan ce and reference for mining at the fully mechanized caving coal face on similar conditions.
