摘要
在地质条件复杂长壁综合机械化开采效率低、煤质无法保证、经济效益差,通过短壁连续采煤方法的探索应用,保证了煤质,提高了吨煤售价,取得了较好的经济效益,对复杂地质条件下短壁机械化开采有很好的参考价值。
Demonstrates the complex geological conditions of the long arm of the comprehensive mechanized coal mining, coal can not guarantee the low efficiency and poor economic performance situation, through the continuous application of short wall mining method, ensure the quality, improve the price per ton of coal has achieved good economic benefits, demonstrates the feasibility and complex conditions of short wall mining the safety and economy.
