探讨膏体充填开采技术在煤矿采空区的应用

Discussion on Application of Paste Filling Mining Technology in Mined-out Area of Coal Mine

膏体充填开采技术是煤矿开采行业的重要技术形式,本文简述膏体充填开采的作用,辨识导致开采期间地表沉陷的关键因素,引入工程实例,系统性地探讨膏体充填开采技术在煤矿采空区的应用要点,涉及到材料准备、制浆、充填管路配置等环节,最后评价在采取充填开采技术后的应用效果,得出膏体充填开采技术可减小地表移动变形、提高煤矿采出率的结论。

Paste filling mining technology is an important technology of the coal mining industry,the article briefly describes the role of the paste filling mining,identify resulting in key factor during the mining surface subsidence,the introduction of an engineering example,systematically discusses the application of paste filling mining technology in coal mine goaf,involved in materials preparation,pulping,filling line configuration.Finally,the application effect of the backfill mining technology is evaluated,and the conclusion is drawn that the paste backfill mining technology can reduce the surface movement deformation and improve the coal mine recovery rate.
