大倾角特厚煤层综放工作面液压支架选型设计

Support Selection Design of Fully Mechanized Caving Face in Large Dip Angle and Thick Coal Seam

根据某矿大倾角特厚煤层综放工作面的地质开采条件,通过理论计算及分析,确定基本液压支架选用ZF7800/19/38型液压支架;端头液压支架采用三架一组ZT21600/21/38型中置式放顶煤端头液压支架;过渡液压支架选用7架ZFG8600/21/38型放顶煤过渡液压支架,采用"头三尾四"布置方式。

According to the geological mining conditions of fully mechanized caving face with large dip angle and extra thick coal seam, through theoretical calculation and analysis, it is determined that the basic support is ZF7800/19/38 type hydraulic support, and the end support adopts three sets of ZT21600/21/38 type middle caving end head hydraulic support. There are 7 ZFG8600/21/38 top coal caving transitional hydraulic supports with ＂first three tail four＂ arrangement.
