摘要
通过硬厚煤层综放开采顶煤弱化技术的全面调研,确立不同开采条件的顶煤弱化工艺模式。结合现场工业性试验,验证架间爆破方案的可行性,指出存在的具体问题和今后发展方向。
Through roundly investigating and researching of intenerating technique of top coal in top coal caving hard thick coal seam, this paper establishes intenerating technique mode of top coal under different mining condition. Combining spot technical examination, validating feasibility of dynamite between supports, the author indicated the detail problem and developmental aspect.
