摘　　要：根据龙王沟煤矿6#煤层工作面开采相似模拟试验所获取的工作面大采高大放高液压支架在初次来压及周期来压时的工作阻力及煤壁的超前支承压力分布数据,对比分析了在6上煤层已采的情况下(采空区下)开采6#煤层时液压支架的工作阻力及煤壁超前支承压力的分布情况,找出了合理的工作面支架支护参数,为现场生产提供了科学依据。By supporting the work of the resistance ahead of a similar simulation of Longwanggou thick coal seam No. 6 coal face,get a large mining coal face tall hydraulic supports in place high initial pressure and pressure cycles when and coal wall pressure data and comparative analysis of the coal seam in 6 cases have been taken under(under Gob) when No. 6 coal mining hydraulic support working resistance and coal wall abutment pressure,find a reasonable parameters of Working face supporting bracket for field production guidance provides a scientific basis.
