摘　　要：新郑煤电公司支架组装间为托顶煤硐室,为解决施工距离短、断面大、开口施工难度较大、顶板管理及围岩变形控制困难等施工技术难题,从工程煤体固化、主被动耦合支护、壁后充填等方面进行了大断面托顶煤硐室施工技术研究。经矿压观测检验,巷道变形量很小,效果良好。The support assembly room of Xinzheng Coal and Power Company is a roof supporting coal chamber.In order to solve the construction technical problems such as short construction distance,large section,difficult opening construction,difficult roof management and surrounding rock deformation control.The construction technology of large section roof coal chamber is studied from the aspects of engineering coal body solidification,active and passive coupling support,back wall filling and so on.By means of observation and inspection of ore pressure,the deformation of roadway is small and the effect is good.
