钢丝绳锯走向长壁采煤工艺的实践

在七台河矿区,急倾斜薄煤层开采所占比重较大,采场条件差,单产较低,危险性高。急倾斜薄煤层安全高效开采一直是亟待解决的难题。东风煤矿通过在适宜条件下,应用钢丝绳锯采煤工艺取得成功,达到了无人工作面安全高效开采的目的。

Practise of Mining Technics of Sawing Longwall along Strike by Steel Wire Rope

The percent of steep thin seam is greater in Qitaihe coal mining area.The condition is complicated,the production is low and high-risk in mining in coal mining face in the steep thin seam.The mining in the steep thin seam with high security and high efficient is a very difficult question which needs be solved.The coal mining technology which using wire rope saw is successful,it is safe,efficient and without worker in the coal mining face in the steep thin seam.
