中文摘要：
针对采空区下近距离煤层综采工作面支架支护强度确定的难题，采用理论分析方法给出了近距离煤层的定义，并按照支架的力源将采空区下近距离煤层开采时的顶板分为“采空区下”、“实体煤下”和“煤柱下”三种类型。针对不同类型顶板结构，对工作面顶板进行分类，分析综采工作面支架一围岩关系，给出了确定支架工作阻力的定量计算公式，确定了支架支护强度并在现场工程实践中得到验证。研究结果可为类似条件下支护栽荷的选择提供理论依据和工程参考。
英文摘要：
To solve the problem of how to determine the sup- porting strength in fully mechanized mining face of close dis- tance coal seam under goal, the definition of close distance coal seam was given based on the theoretical analysis meth- od. According to different support forces, the roofs were di- vided into three types., under goaf, under solid coal and un- der coal pillar. With regard to different types of roof strata structure, the working face roofs were classified, the rela- tionship of support and surrounding-rock in fully mechanized mining face was analyzed, the quantitative calculation formu- la for determining the working resistance of the support was developed, and the supporting strength was determined and verified through field engineering practice. The research re-sults can provide theoretical basis and engineering reference for selecting supporting load under similar conditions.
