王庄煤业3~#厚煤层大采高开采可行性探索与研究

A study on the feasibility of high seam mining in #3 thick coal seam of Wangzhuang Coal Mine

结合王庄煤业3#煤层及顶板岩石力学特性,论述了该矿厚煤层采用大采高开采的可行性,提出了大采高综采工作面液压支架强度及稳定性的设计要求,给出了3043大采高综采工作面设备配套选型方案及主要生产系统的升级改造内容与实施计划。

On the basis of the mechanical characters of Wangzhuang Coal Mine＇s # 3 coal seam and that of its roof strata, the author discusses the feasibility of using high seam mining technique to produce coal from the thick coal seam of this mine and puts forward designing re- quirements for the strength and stability of hydraulic supports to be used in the high seam mining longwall face. The author also provides the integrated equipment selection scheme for the high seam mining longwall face as well as the technical upgrading scheme and its implementation plan for the major production systems involved.
