以早期煤巷掘进过程中揭露的围岩地质资料为基础,针对在煤巷掘巷和维护期间遇到的围岩易离层、片帮问题,深入研究了早期煤巷围岩变形机理,对煤巷掘进施工工艺和联合支护形式进行了优化,并应用数值模拟对新支护方案进行了分析,最后通过工程实例验证了新支护参数的合理性,为今后煤巷联合支护提供了经验。 Based on the geological data of surrounding rock exposed in the process of early coal tunneling, the deformation mechanism of surrounding rock in early coal roadway is deeply studied in view of the problems of the wall rock separation and sheeting during tunneling and maintenance of coal roadway. Coal roadway excavation construction technology and the form of joint support are optimized, and the new support scheme is analyzed by numerical simulation. Finally, the rationality of the new support parameters is verified through the engineering example, which provides the basis for the future coal roadway combined support experience.
