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 ,为下区段确定合理煤柱尺寸及沿空掘巷的支护方式提供分析依据
According to the observation data of the gob-side entry pressure of the 32 2 7 fully mechanized top-coal caving mining face in Rujigou Mine, Ningxia, the law of occurrence of gob-side entry pressure is analyzed and summarized based on the theory of mine pressure. The mechanical model provides the basis for determining the reasonable coal pillar size and the supporting way of roadway driving along the next section
