- In flat dip layer, the seam thickness control the stability of the wall rock, the thick-bedded hard rock is stable than the thin-bedded hard rock. 巖層厚度在緩傾斜時(shí)對圍巖穩定起控制作用，厚層硬巖整體穩定性好于薄層狀硬巖。
- Using numerical value test based on the wave velocity function of the transverse isotropic elastic medium, the two effects are validated. 從橫觀(guān)各向同性彈性介質(zhì)的波速方程出發(fā)，通過(guò)具體的算例對這兩種特征進(jìn)行了較好的理論分析。
- Then a 2D velocity function was used to approximate the velocity distribution of entrained flow to simplify the fundamental equation. 然后用一個(gè)二維函數來(lái)近似引射流的速度分布，對導出的基本方程進(jìn)行簡(jiǎn)化；
- By treating the rock as the transverse isotropic elastic medium and using numerical test of the wave velocity function, the property is theoretically validated. 基于橫觀(guān)各向同性彈性介質(zhì)的波速方程，還進(jìn)一步通過(guò)具體算例對這特征進(jìn)行較好的理論分析。
- Application of caving mining technology with bottom under condition of flat dipping mid-thick body and unstable rock caused the most of trench and bottom drift, located in abutment , to be destroyed and low recovery in south area, Xishimen Iron Mine. 摘要在緩傾斜中厚礦體底板巖性不穩固的條件下，采用有底柱崩落法，由于電耙道大多處于空區邊部應力集中的部位，致使塹溝及底部結構巷道破壞嚴重而使回收率極低，采用無(wú)底柱崩落卸壓則可有效解決上述難題。
