为了减小或者完全避免地下开采对地表建筑物的有害影响,根据深部开采地表移动的实测数据,本文给出了地表移动和变形预计参数,利用概率积分法对地表任意点的下沉值进行计算,分析了建筑物受地下开采的影响程度,以此对矿区地表建筑物保护煤柱进行设计。研究表明,基于地表移动和变形预计理论的保护煤柱设计方法,对减少深部开采保护煤柱的压煤量、保护地表建筑物、实现地下煤炭开采的可持续发展具有一定的参考价值。
In order to reduce or completely avoid the detrimental effect of underground mining on the surface buildings, according to the measured data of surface mining in deep mining, the prediction parameters of surface movement and deformation are given, and the settlement value of arbitrary point on the ground is calculated by using the method of probability integration , Analyzed the impact of the underground mining of buildings, and designed the coal pillars of surface buildings in the mining area. The research shows that the design method of protection coal pillar based on the theory of surface movement and deformation prediction has certain reference value to reduce the amount of coal in the deep mining protection coal pillar, protect the surface buildings and realize the sustainable development of underground coal mining.
