Study on the Application of Pillar Free Mining Technology in Large Mining Height Face of Thick Coal Seam

为了有效提高某煤矿厚煤层大采高工作面的煤矿开采工作效率,采用了无煤柱开采工作技术,通过具体的实验室实验分析和工业性实验结果之间进行结合,对大采高工作面无煤柱开采技术展开了全面分析和研究,依照柔模混凝土力学性能以及相关的实验工作,结果得出柔模混凝土的强度,高于普通混凝土的施工强度,使得无煤柱开采作业得到实现,整体的矿井生产经济效益更加明显。

In order to effectively improve the mining efficiency in large mining height working face of thick coal seam,the coal pillar free mining technology is adopted.Through the combination of specific laboratory experimental analysis and industrial experimental results,the coal pillar free mining technology of large mining height working face is comprehensively analyzed and studied.According to the mechanical properties of flexible concrete and related experimental work,the results show that the strength of flexible concrete is higher than the construction strength of ordinary concrete,so that the coal pillar free mining operation is realized,and the overall economic benefit of mine production is more obvious.
