以亭南煤矿1102宽条带矸石充填工作面为工程背景，采用理论分析、数值模拟、室内试验、现场实测等方法研究了矸石机械压缩过程及岩层沉降规律。结果表明：散体矸石经2 MPa夯实后压缩了27.05%，变成矸石充填体，矸石充填体在可充填空间内机械压缩过程及架后压缩率为（各阶段压缩与可充填空间高度比值）：骨架调整段（7.42%），缓慢压缩段（5.39%）；机械压缩等价采高为可充填空间高度与矸石充填体2个阶段可充压缩率的乘积；1102工作面矸石充填体在骨架调整段和缓慢压缩段的等价采高分别为0.94 m和1.10 m；1102工作面走向和倾向主断面地表下沉曲线均为“碗”形，骨架调整段到缓慢压缩段过程中，地表变形曲线变化不大，最终最大下沉量分别为39 mm和41 mm。

Taking 1102 gangue filling face of Tingnan Coal Mine as the research object, theoretical analysis, numerical simulation, laboratory test and field measurement were used to study the process of gangue compression and the law of strata subsidence. The results show that: after 2 MPa compaction, the bulk gangue is compressed by 27.05 % to become gangue filling body, the mechanical compression process of gangue filling body in fillable space and the compression rate (the ratio of compression amount in each stage to fillable space height) are: skeleton adjustment（7.42%）, slow compression (accounting for 5.39%); the equivalent mining height of mechanical compression is the product of the fillable space height and the second-stage fillable compression rate of gangue filling body. The equivalent mining height of gangue filling body in 1102 working face in skeleton adjustment and slow compression is 0.94 m and 1.10 m respectively; the surface subsidence curves of the main section of 1102 working face in strike and inclination are all in the shape of “bowl”. During the process from skeleton adjustment to slow compression, the surface deformation curve changed little, and the final maximum subsidence was 39 mm and 41 mm, respectively.
