【摘要】 针对具体的煤层条件和围岩特点进行支护参数的量化设计,是锚网支护技术发展的必然趋势。采用锚网支护方式维护厚煤层放顶煤沿底回采巷道时,多数需要考虑锚索加固问题。在综合讨论大屯矿区现用锚网支护设计方法尚存问题的基础上,对厚煤层放顶煤沿底回采巷道的锚网(索)支护参数设计方法进行了全面分析。更多还原

【Abstract】 The quantitative designing of the support parameters according with the occurrence of coal seam and the seam condition is inevitable tendency in development of bolting support technology. The bolting with wire mesh is commonly used actual mining roadway of the thick coal seam, and in some cases the cabling reinforcement should be considered. Based on the multiple problems existing in design of bolting support in Datun Mining Area nowadays, the parameters of bolting (cabling) with wire mesh in actual mining roadway of thick coal seam by caving method are systematically studied in the paper.更多还原
