摘　　要：为有效解决松软破碎地层中的大断面硐室施工难题,运用理论分析、数值模拟等手段,对硐室施工进行了研究。通过合理选择大断面硐室施工工艺和支护参数,形成了一套集多项技术于一体的大断面硐室掘砌技术体系。毛坪铅锌矿探矿竖井天轮硐室采用该项技术施工,在安全、质量及进度等方面,均取得预期效果,为类似矿山深部复杂条件硐室施工提供了经验。In order to effectively solve a difficult construction of a large cross section chamber in a soft and broken strata,a theoretical analysis,numerical simulation and other means were applied to study the chamber construction.With the rational selection of the construction technology and the support parameters for the large cross section chamber,a set with several technologies was formed as an integration excavation and lining technical system of the large cross section chamber.This technical construction was applied to the hoisting sheave chamber of the mine shaft.The expected effects on the safety,quality,schedule and other aspects were obtained and the technical construction could provide the experiences to the chamber construction complicated conditions of the simulate mine complex conditions.
