摘　　要：基于红庆河煤矿井底箕斗装载硐室围岩条件及地应力条件,分析了硐室结构优化的可能性,采用现场调研、数值模拟和现场实测等分析方法,设计提出了硐室"断面简单化、个数单一化、受力合理化"设计理念。通过工程实践表明,与传统箕斗装载硐室相比,该硐室设计理念及布置形式能大幅度降低硐室复杂程度,简化箕斗装载硐室施工程序,降低了施工难度,提高了硐室适用围岩应力变化的能力,满足特大型煤矿箕斗装载硐室对空间、安全、运行、工作环境的要求。Based on the rock conditions and stress conditions of the shaft-bottom skip loading chamber of Hongqinghe Coal Mine,the optimization feasibility of the chamber structure was analyzed,and the analysis methods of field investigation,numerical simulation and field measurement were adopted,and the design concept of ＂simple section,simple number,rational force＂was proposed for the chamber. Through engineering practice,it is shown that compared with the traditional skip loading chamber,the proposed chamber design concept and layout form can greatly reduce the complexity of the chamber,simplify the construction procedures, reduce the construction difficulty, and improve the adaptability of the chamber to the change of surrounding rock stress,so as to meet the requirements of extra large coal mine skip loading chamber for space,safety,operation and working environment.
