摘　　要：为更合理的留设安全煤岩柱尺寸,减少资源浪费,有必要研究特殊结构覆岩"两带"高度的计算方法。采用公式计算、类比分析及数值模拟方法,分别计算出研究区域内中硬偏软特殊结构覆岩下的"两带"高度。通过与"两带"高度现场实测结果的对比分析,综合研究了浅部区域中硬偏软覆岩条件下"两带"发育高度特征及其计算方法。To design rational height of safety coal pillars, and reduce resource waste, it is necessary to study calculation method of ＂two zones＂ height for special structure overburden. This paper adopts the formula calculation, analogy analysis and numerical simulation methods to calculate separately the damage height of special structure overburden. The features and calculation method for development height in middle hard leaning soft overburden of shallow area are studied through analyzing eontrastively the results obtained by actual nhservation and other methods.
