摘　　要：目前近距离煤层联合开采工作面错距理论基本有2种形式:第1种是稳压区布置形式,相对安全,得到了当前的普遍认可;第2种是减压区布置形式,这是相对危险的错距布置形式。本次研究探索采用传统矿压、弹性半平面体理论相结合的研究方法,考虑了上煤滞后支承压力对层间应力分布的影响,对近距离煤层联合开采条件下工作面合理错距的留设问题进行研究,得出错距的计算公式。At present, the staggered distance theory of combined mining face in close distance coalseam has two basic forms： the first, stable-pressure layout form is relatively safe, has been generallyrecognized in the current; the second is reduced-pressure zone layout form, which is the relativedangerous misplace layout. This study and explore considering the abutment pressure influence to thestress distribution between layers ,using the traditional rock pressure and elastic semi plane theory toanalyze the issue of the coal face reasonable deviation of the combined mining face under the conditionof the coal seam, and conclude the computational formula of the staggered distance.
