In order to reduce the coal loss and increase the rate of recovery,the new mining methods are adopted,which is false inclination mining,top tunnel outward mining,and bottom tunnel outward mining.
为了减少煤炭损失,提高回采率,采取新的回采方式,即伪倾斜开采和上巷前进式、下巷前进式回采,使煤炭损失量降低到最小程度,提高了经济效益。
6) pitching oblique mining
俯伪斜开采
1.
Aimed at the problem on protection scope demarcation of upper steeply inclined protective seam of pitching oblique mining,based on the method of three dimensional fast Lagrange method,the dynamic development process of stress distribution and deformation of protected coal seam with exploitation of steeply inclined protective seam of pitching oblique mining were simulated using FLAC~(3D).
针对急倾斜煤层上保护层俯伪斜开采的保护范围划定问题,采用三维快速拉格朗日法,通过模拟上保护层俯伪斜开采后被保护层的应力场及变形场的动态发展过程,确定了随着上保护层工作面的推进,被保护层的垂直层理面应力和煤层变形规律;根据上保护层开采后的应力卸压保护准则和煤层变形保护准则,确定了上保护层沿走向和倾向的保护范围。

火力掩护
fire cover
huoli yanhu火力掩护(fire cover)保障军队或重要目标安全的火力突击。有时专指进攻作战中保障部队开进、展开时的火力突击。目的是保障部队顺利地遂行作战任务或实施机动。对空火力掩护主要由防空兵担负。一般采取固定掩护、要点掩护、跟进掩护、交替掩护和伴随掩护等方法。地面火力掩护主要由炮兵、战役战术导弹部队和航空兵担负。进攻作战时，火力掩护的主要任务是保障部队顺利安全的开进、展开和占领进攻出发阵地;掩护进攻战斗队形上空的安全等。防御作战时，火力掩护的主要任务是掩护预备队机动和向敌实施反冲击、反突击;掩护阵前障碍物和接合部的安全;掩护换班和防御部署上空的安全，掩护撤离防御地区等。军队移动和驻止时也组织火力掩护。(徐国成)
