- Vertical stress makes rock stratum reforming voussoir beam, horizontal in-situ stress is the main source to cause the voussoir beam crushed. 豎直方向地應力使頂板岩層形成鉸接拱結構,水平地應力是拱鉸壓碎的主要力源。
- One of the crucial elements influencing the rock burst is the structure of roof rock stratum, especially the flinty and thick sandstone roof over the coal seam. 頂板岩層結構,特別是煤層上方堅硬、厚層砂岩頂板是影響衝擊礦壓發生的主要因素之一。
