缓倾斜煤层过地质构造断层带技术研究

Research on Technology of Gently Inclined Coal Seam across Geological Faults

通过对缓倾斜煤层地质构造断层带性质及对回采影响范围的分析,结合以往过断层的经验,对施工成本、产量及安全等多方面进行比较,提出了工艺巷配合大直径深孔预裂爆破岩石实现综放工作面安全、快速地通过断层的技术方案,实现综放工作面过断层安全回采。

With thorough understanding and analysis on geological faults and related influential range of recovery of inclined coal seam, taking into account the past experience of going through faults, comparing cost, production and safety, a technical program is put forward for fully mechanized face going through faults quickly and safely when technical tunnel works together with large-diameter deep hole presplitting blasting rock. Research and proposal of parameters such as tunnel layout, advancement and large-diameter deep hole presplitting blasting, make safe recovery of fully mechanized face across faults possible, which could be refered to for minging on gentle inclined coal seam geological faults.
