兖州兴隆庄矿在1307综放工作面上方设立了3条地表移动变形观测线,以获得不同表土厚度或采深条件下地表移动参数,为今后合理留设铁路及建筑物保护煤柱提供依据。通过对实测资料的总结分析,得到了该区综放开采条件下的地表移动变形规律、各种角值参数和预计参数,并对边界角、移动角进行了相关分析研究,研究成果为今后类似条件下各类建(构)筑物下采煤提供了科学依据。
Xinglongzhuang Colliery have set up 3 surface subsidence observation lines over 1307 Full-mechanized Caving Mining Face for obtaining surface movement parameters under the condition of different topsoil depths and buried depths and providing basis for reasonable railway and buildings protective pillar design. This paper analyzes these observation data and acquires surface deformation rules, various angle parameters and prediction parameters under different full-mechanized caving mining condition in this area. It also analyzes angle of subsidence and angle of critical deformation. These results provide scientific reference for mining under buildings.
