【摘要】 构造应力场研究是地球科学研究的主要内容之一,是我们进行各种地学工程所必须研究的对象,是分析各种地质构造运动的基础,是地球动力学研究中的重要组成部分。在煤炭工业的地质勘探阶段一直到生产阶段,以及生产的全过程,构造应力都具有极其重要的地位,是煤炭开采过程中解决各种问题的基础和前提。 本次研究是应用地质动力区划方法,以吕家坨井田为研究对象,查明井田地质构造,建立地质构造模型,通过岩体应力状态分析系统,在宏观上对矿井区域进行分析,从而得到井田区域的合理预测,对煤矿的工作面生产和采区巷道的合理布置提供基础数据,预测矿井矿压显现严重的区域,保证矿井安全生产。

【Abstract】 Tectonic stress field is one of main content of earth science, the object of researching earth science engineering, the base of analyzing all kinds of geological tectonic movement, and the important part of the Geo-dynamics. From the geologic exploration, mining, to the whole mining processes, Tectonic stress is very important, and become the precondition and base of solving all problems in the process of coal mining.Geo-dynamic Division method is applied to research the Lujiatuo Minefield, so the geological structures are identified, and the model of geological structure is founded. By the Rock Mass State Analysis System, the mine regions are analyzed in the whole, and then the mine regions are forecasted reasonably. These results provide fundamental data for the excavation of coalfaces and reasonable layout of the district tunnels. The regions of severity emergence of mine pressure are forecast, which is benefit for the safe production.
