摘要
针对回采巷道在以胶结性极差的离层型薄页岩为顶板的地质条件下,根据围岩矿物成分分析,提出了合理的支护方式,并对其进行矿压观测,验证了支护方式的正确性,并为类似地质条件下的回采巷道支护提供借鉴。
Against working roadway badly bounding capacity geological conditions, and according to assay of adjacent rock mineral component, achieving rational support way, and then doing mine press observation, proving the support way is correct, supply experience to the similar geological conditions roadway support.
