摘　　要：为了解决公路及天然气管道压覆的保护煤柱使得煤炭资源造成了很大浪费的问题。通过现场试验法和工程类比法对CT31101首试面进行膏体充填条带开采。结果表明:支巷沿空采煤最优控顶距为5 m,第一试验段支巷保护煤柱5.5 m,第二试验段支巷保护煤柱为6 m。保证膏状浆体中小于0.075 mm的细小颗粒物比例达到20%以上可以保证膏体充填的接顶密实率。应用后地表最大水平变形为0.93 mm/m,地表最大倾斜变形2.8 mm/m,地表最大曲率0.04×10^(-3)mm/m,符合要求。In order to solve the problem that the protective coal pillars covered by highways and natural gas pipelines have caused a great waste of coal resources.The paste filling strip mining was carried out on the first test surface of CT31101 by field test method and engineering analogy method.The results show that the optimal roof control distance of gob-side entry mining is 5 m,the protective coal pillar of the first test section is 5.5 m,and the protective coal pillar of the second test section is 6 m.which ensures that the proportion of fine particles less than 0.075 mm in the paste slurry reaches more than 20%to ensure the roof compactness of the paste filling.The maximum horizontal deformation of the surface is 0.93 mm/m the maximum tilt deformation of the surface is 2.8 mm/m and the maximum curvature of the surface is 0.04×10^(-3)mm/m,which meets the requirements.
