1) 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。
2) oblique mining
伪俯斜开采
3) sloping mining approach
俯斜开采
1.
The sloping mining approach will lead to high productivity and efficiency and result in better economic benefits.
对陈四楼煤矿21108综采工作面大倾角俯斜开采中所遇到的技术管理难题进行了分析,特别指出了在设备防滑、防窜矸、皮带巷防煤(矸)滚落伤人等方面的安全技术管理难点和重点,提出了解决问题的有效措施,使大倾角综采工作面俯斜开采实现了高产高效,取得了较好的经济效益,为大倾角综采工作面俯斜开采积累了经验。
4) down-dip strip mining
俯斜式开采
1.
In order to effectively use resources to enhance mine recovery rate,the paper studied down-dip strip mining method under the village,different plans were compared based on the actual situation.
为了有效利用资源,提高矿井采出率,对村庄下压煤区域条带开采方法进行研究,根据实际情况,进行方案比较,认为采煤工作面沿走向布置,倾向向下推进、俯斜式开采优点突出,应用该方法可以缩短采面准备工期,提高产能,实现连续生产。
