抚顺东露天矿西部坑底采煤工艺优化

Optimization of mining technology in Fushun East Open-pit Mine western pit

抚顺东露天矿西部坑底煤炭采区是东露天矿重点煤炭采区,其开采至煤层顶板(2W2台阶)时,上部覆盖的"三角"贫矿量严重加大了汽车露煤工程量,影响煤炭采区推进及降深进度。因此,需要电铁工艺与汽车工艺优势互补,充分发挥各自效率,加快"三角"贫矿露煤工程量采掘进度,保证全年煤炭供应任务的顺利完成。

The pit bottom of western coal mining area is key coal mining area in East Open-plt Mine. When the coal seam roof （step 2W2）, the upper cover of ＂triangle＂ serious lean ore increases the car exposed coal quantity, and affects coal mining area advance and drawdown schedule. Therefore, the electric iron technology and automotive technology are given full play to their respective advantages, speeding up the ＂triangle＂ lean coal quantity dew mining progress to ensure the successful completion of the annual coal supply task.
