矿区建筑物下保护煤柱的决策与分析

Decision and Analysis of Buildings for Protective Coal Pillar Method in Mining Area

为了保护地面建(构)筑物免受井下开采而引起的破坏,选取实际生产中常用的垂直剖面法和垂线法分别研究了在不同开采深度、不同煤层倾角及不同走向(指与建筑物主走向)等情况下的压煤量。通过分析比较,得出了不同条件下2种方法压煤量的关系,并对部分特殊建(构)筑物以及特殊地质条件下的情况进行了分析说明。研究结果可为地上建筑物的保护提供依据,从而指导不同条件下煤炭资源的合理开发。

In order to protect the ground built(structure) structures from damage caused by underground mining, commonly select the vertical section method and vertical method studied under different mining depth, dip angle of coal seam and different trends(and building owners to) of the coal amount of circumstances. Through the analysis comparison in actual production, it obtains the pressure coal relationship of the methods in different conditions. Made simple analysis of the part under the condition of special built and special qualities. The results provide the basis for the protection of the buildings on the ground, the rational development of coal resources and guidance under different conditions.
