目前,我国煤矿建设中出现了大量的工程地质问题,致使基建矿井长期达不到设计能力。文章就此阐述了在煤田勘探阶段就对围岩的稳定性作出评价的迫切性,并指出地质部门应向设计部门提交巷道围岩稳定性工程地质分类的图件,为选择开拓方案、支护方法提供依据。文章还在潘二、潘三井1500m巷道调查的基础上,得出影响巷道围岩稳定性的四个主要因素,及岩体稳定类型的分类。
At present, a great deal of engineering geological problems have emerged in the construction of coal mines in our country, resulting in the long-term under-design of infrastructure mines. This article elaborates on the urgency of evaluating the stability of surrounding rock in the coal exploration stage and points out that the geological department should submit to the design department the pictures of the geological classification of the surrounding rock stability engineering for the selection and development plan, Provide evidence. Based on the survey of 1500m roadway of Pan 2 and Pan Mitsui, the article draws four main factors that affect the stability of roadway surrounding rock and the classification of rock stability type.
