摘要
大部分矿区煤层处于较深的位置,地质条件十分复杂,在煤矿开采的过程中,需要花费较长时间来准备巷道,因此需要钢管混凝土拱架来确保巷道的质量和稳定性。首先对煤矿软岩巷道中钢管混凝土拱架的应用发展和技术特点进行分析,其次对煤矿软岩巷道中钢管混凝土拱架的应用理论进行探析,最后对煤矿软岩巷道中钢管混凝土拱架应用过程中存在的科学问题及解决策略进行研究,希望能够为钢管混凝土拱架在煤矿软岩巷道中的应用提供一些参考和帮助。
Most of the coal seams in the mining area are in a deep position,and the geological conditions are very complex.In the process of mining,it takes a long time to prepare the roadway,so the concrete-filled steel tube arch is needed to ensure the quality and stability of the roadway.This paper first analyzed the application and development and technical characteristics of concrete-filled steel tube arch in the soft rock roadway of coal mine,then analyzed the application theory of concrete-filled steel tube arch in the soft rock roadway of coal mine,and finally studied the scientific problems and solutions in the application process of concrete-filled steel tube arch in the soft rock roadway of coal mine,hoping to provide some reference and help for the application of concrete-filled steel tube arch in the soft rock roadway of coal mine.
