摘要： 针对A 矿15 号煤层综采工作面周边采空区积水量较大、对煤矿安全生产影响较大的问题，运用理论分析、数
值模拟方法，计算出导水裂隙带高度介于68.5～166.8 m，平均102.3 m。通过数值模拟可知，随着煤层采高、工作面开采
长度、倾角的增加，覆岩“两带”发育高度也呈持续增加的趋势，最终确定15 号煤层开采“两带”高度在59.5～166.8 m，
平均范围在68.1～102.3 m，为15 号煤层的安全开采提供了依据。

Abstract: Aiming at the problem of a large amount of water in the goaf surrounding the fully mechanized mining face of No.15
coal seam in A Coal Mine, which has a greater impact on coal mine safety production. In this paper, the theoretical analysis and
numerical simulation methods were used to calculate the height of the water conducting fracture zone to be between 68.5-166.8 m,
an average of 102.3 m. Through numerical simulation, with the increase of coal seam mining height, working face length, and
inclination angle, the development height of the overlying strata "two zones" also showed a continuous increase trend. It was
finally determined that the height of the two mining zones of No.15 coal seam was 59.5-166.8 m, with an average range of 68.1-
102.3 m, providing a basis for the safe mining of No.15 coal seam.

Key words: fully mechanized mining face; numerical simulation; water conducting fracture zone; development height
