急倾斜厚煤层综采安全技术研究

Research on safety technology of fully mechanized coal mining in steep inclined thick seam

本文以长城二矿1901S急倾斜厚煤层长壁综采工作面为例,研究并成功提炼工作面设备防倒、防滑、工作面防飞矸等安全开采技术,实现了急倾斜厚煤层综采工作面一次采全高的安全高效开采,对同等条件下的煤层开采具有重要借鉴意义。

There are many problems in the process of mining steeply inclined thick coal seam, such as roof management is difficult, equipment is difficult to be stable, safety is difficult to guarantee and so on, this is also the main difficulty of steep thick seam mining, taking ChangCheng NO.2 mine 1901S steeply inclined thick seam longwall face as an example, actively and successfully enriched the working face equipment anti-inverted, anti-skid, anti fly waste safety mining technology, and realized the steeply inclined thick coal seam fully mechanized working face a mining full height safety and high efficient mining, which has a great significance under the same conditions of coal seam mining.
