西德Warndt矿应用现有技术已经能够开采厚度范围为1.3～4m的煤层。工作面的设备包括:无线电遥控、双牵引销轨式无链牵引采煤机,2×26×92双中链PFⅡ/30或EKFⅢ型刮板输送机,四连杆式掩护支架和一部分还在用的圆弧式掩护支架,每15m的中间锚固点及控制站。各采煤机和支架的造型取决于所采煤层的厚度,现在的分界线在2～2.2m。小于2.2m使用EDW300—LE1200或EDW200/230—LN型双滚筒采煤机和支撑高度0.9～2.4m的二柱四连杆式掩护支架;大于2.2m用的设备为EW300—L型单滚筒采煤机和支
The existing technology at Warndt in West Germany has been able to mine a coal seam with a thickness ranging from 1.3 to 4 m. Face equipment includes: radio remote control, double traction pin rail chain-free haulage shearer, 2 × 26 × 92 double-chain PFⅡ / 30 or EKF Ⅲ scraper conveyor, four-link shield bracket and some still Used arc shield bracket, the middle of each 15m anchor point and control station. The shape of each shearer and support depends on the thickness of the coal seam being seamed. The current boundary is between 2 and 2.2 m. Less than 2.2m The use of EDW300-LE1200 or EDW200 / 230-LN double drum shearer and support height of 0.9 ~ 2.4m two-column four-link shield bracket; equipment greater than 2.2m for the EW300-L-type single drum mining Coal machine and branch
