摘要
针对神农煤业15号煤层赋存地质条件,结合矿井设计采煤方法,根据"传递岩梁"理论,对工作面液压支架支护强度、工作阻力以及支架高度进行了分析,确定了工作面采用ZZ8000/23/47型四柱支撑掩护式液压支架可满足安全生产。矿压观测表明,工作面液压支架额定工作面阻力具有一定的富余量,取得了良好的支护效果。
In view of the geological conditions of No.15 coal seam in Shennong Coal Industry,combined with the coal mining method of mine design,according to the theory of"transfer rock beam",the support strength,working resistance and support height of hydraulic support in the working face are analyzed,and it is determined that the ZZ8000/23/47 type four column support cover type hydraulic support can meet the safety production.Mine pressure observation shows that the hydraulic support of the working face has a certain amount of surplus resistance and has achieved good support effect.
