In order to solve the problem of high gas emission in coal seam and goa in DaiChiBa coal mine, the technology of flexibility support with wholly mining are adopted.The paper introduces the principle of flexible formwork supporting along the gob side entry retaining technology, combined with the specific geological conditions in No.31342 working face, formed the overall scheme of strengthening support in current roadway and independently support ahead of the current roadway, and parameters for the flexible support and concrete pouring are collected, and the aftermath monitoring and evaluation also carried out.Engineering practice shows that the design of the flexible support can effectively control the deformation of the surrounding rock , ensure the safety, reduce the size of coal pillars, lift the recovery rate.%代池坝煤矿针对煤体与采空区瓦斯涌出量高、留巷矿压显现剧烈等问题,采用了柔模支护完全开采配套技术.介绍了柔模支护沿空留巷技术的原理,结合该矿31342工作面机巷具体地质条件,形成了巷内加强支护与超前隔离支护的总体方案,确定了柔性模板和混凝土浇筑参数,并对巷旁支护体特性与留巷支护效果进行监测和评估.工程实践表明,所设计的柔模支护能够控制住围岩变形,保证后期安全生产需要,有效地减少煤柱留设,提高了回采率.
