在埋深大、构造发育且煤层结构松散等复杂地质条件下，对特厚煤层顺槽进行沿底托顶煤掘进，通过确定合理的支护参数，选用高强扭矩预应力锚杆，并辅以锚索补强，保证了顶板稳定性，实现了安全支护前提下的快速掘进。
在埋深大、構造髮育且煤層結構鬆散等複雜地質條件下，對特厚煤層順槽進行沿底託頂煤掘進，通過確定閤理的支護參數，選用高彊扭矩預應力錨桿，併輔以錨索補彊，保證瞭頂闆穩定性，實現瞭安全支護前提下的快速掘進。

Complicated geological conditions, as deep buried depth, developed structure and loosed coal seam, are always disadvantageous to stability of crossheading advancing along the floor of very thick coal seam. Determining reasonable parameters to control its stability, including reinforced prestressed bolt and cable anchor, roof strata of crossheading may be stable, which is premised to quick and safe drivage
