摘要
本文根据宁夏汝箕沟矿 32 2 7综放试采面沿空掘巷矿压观测数据 ,由矿压理论总结分析其沿空掘巷的特有矿压显现规律 ,并提出区段煤柱受力力学模型 。
Based on the spot observing data about gob entry in fully-mechanized top caving testing face of Rujigou Coal Mine, NingXia province, and according to the strata pressure theory, this paper summarizes its own strata behaviors, gives the pressed mechanical-model of section coal pillar, and provides analysis basis while determining proper pillar size and supporting shape of gob entry driving of the coming sections.
