摘要
针对淮南潘二矿厚松散层薄基岩地质条件下1811(1)工作面开采的液压支架选型,采用数值模拟及相似模拟手段,对1811(1)工作面开采三带发育高度进行了分析研究,并最终确定采用ZZ7200-13/26型支撑掩护式液压支架,通过现场矿压显现规律的实测确定ZZ7200-13/26型支撑掩护式液压支架选型的合理性。
Aiming at hydraulic support selection for the 1811(1) face of the second mine of Panji,under the condition of thick alluvium and thin bedrock geological.Numerical simulation and similar simulation are used to analyze and research the developed high of three zones of the face,and ultimately determining to use the ZZ7200-13/26 type chock-shield-type hydraulic support.Then the reasonableness of the ZZ7200-13/26 type chock-shield-type hydraulic support is certified by measuring strata-pressure behavior on the field.
