非充分稳定覆岩下综放沿空掘巷窄煤柱变形机理
Deformation mechanism of narrow coal pillar in the fully-mechanized gob-side entry with incompletely stable overlying strata
摘要
Abstract
els, the pillar can be divided into three zones, viz., fracture zoneA, stable zoneB and fracture zoneC; fracture zoneA is near the roadway while fracture zoneC is near the gob. Because of the asymmetry of the geometric distribution of these three zones, the stable zone is closer to the fracture zoneC. 3) The key to control the deformation of the coal pillar is to control the rotating and slippage of the key block, and its coupling support control method has been proposed.关键词
