摘　　要：结合杨庄煤矿364采区Ⅲ642工作面建下保护煤柱开采实例,就充填开采和不充填开采两种方案进行地表下沉的计算分析,并对地表移动和变形参数的合理选取作了总结,结果表明:用充填巷式开采法对建下保护煤柱进行开采取得了较好效果。Combining with under building protection pillar mining example of Ⅲ642 working surface in 364 mining region of Yangzhuang mine,the paper carries out surface subsidence calculation analysis of backfill mining scheme and unbackfill mining scheme,and summarizes rational selection of surface displacement and deformation parameters.Results show that： it has achieved great effect in under building protection pillar mining with backfill mining method.

关 键 词：建下保护煤柱 地表下沉 地表移动 充填开采
