摘要
支架类型和相关的主要参数对工作面安全生产具有十分重要的意义。结合3-803工作面地质条件及煤层赋存情况,利用数值模拟研究了综放、综采两种采煤工艺液压支架的工作阻力和支护强度。通过理论计算确定了不同采煤工艺液压支架的合理结构高度,并分析了不同数量支柱支架的具体参数。
Stent type and relevant major parameters made a difference in safety production of working face. Combining with geological condition of 3-803 working face and coal seam occurrence in this paper, numerical simulation was used to study working resistance and supporting intensity of two mining technique hydraulic support which were mechanized caving and fully mechanized mining respectively. Reasonable structure height of different mining technique hydraulic supports were determined by theoretical calculation and specific parameters of various quantity of pillar support were analyzed as well.
