庞庞塔矿煤柱综放工作面矿压显现规律研究

Study on the law of rock pressure appearance in coal pillar fully mechanized caving face in Pangpangta Mine

工作面回采后遗留下的大量残留煤柱回收以已成为大型矿井中后期保持矿井稳产、高产亟待解决的紧要问题,为掌握庞庞塔矿煤柱回收综放工作面的矿压显现规律,以一采区91M1煤柱综放工作面为背景进行矿压显现规律实测,通过分析计算等方法得到工作面周期来压规律、支架适应性等重要信息,研究成果对指导庞庞塔矿厚煤层煤柱工作面采场矿压控制意义重大,也为类似条件下煤柱工作面的安全顺利回采提供了参考实例。

A large amount of residual coal pillar resources left behind after working face mining has become an urgent problem to be solved in the middle and later stages of large mines to maintain stable and high production in the mine. Based on the 91 M1 coal pillar fully mechanized caving face in the first mining area as the background to conduct the actual measurement of the mining pressure, through analysis and calculation methods, the working face periodic pressure law,support adaptability and other important information were obtained, the research results guided the Pangpangta Mine thick coal seam working face mining pressure control, and also provided a reference for the safe and smooth mining of coal pillar working face under similar conditions.
