浅析切顶爆破卸压在矿压防治中的应用

Analysis on the Application of Top Cutting Blasting Pressure Relief to the Prevention and Control of Mine Pressure

近年来,随着我国经济的快速发展,工程施工技术不断革新,在矿压防治中常利用切顶爆破技术来治理矿压动力显现。针对旬邑县中达燕家河煤矿有限公司燕家河煤矿回采工作面下山围岩变形严重的问题,运用理论分析和现场实测相结合的方法,分析切顶爆破技术的基本原理,并且以一个工程作为案例进行分析,为广大研究切顶爆破卸压技术预防矿压工作者提供借鉴和参考。

In recent years, with the rapid development of China＇ s economy, the engineering construction technology innovation, often used in the prevention and control of mine pressure blasting technology to control the roof pressure.In view ofyanjiahe coal mine coal mining in Xtmyi County of yanjiahe coal mine limited company facing serious problems down the deformation of the surrounding rock, using the method of theoretical analysis and field measurement by combining the analysis of the basic principle of roof blasting technology, and in a project as a case to analyze, for the majority of top cutting blasting pressure relief technology to prevent mine the pressure of workers and provide the reference.
