摘要
针对试验区的工程地质条件，提出合理的采场与巷道的支护型式、支护参数。引入“等效岩体”概念和边界单元数值方法进行采场支护参数的计算；根据工程经验公式确定巷道支护参数。文中对支护效果进行了评价。
Rational model of timbering of lane and stope and timbering prameters have been proposed based on the engineering geology conditions of test area。“Iso-rochbody”as a new con-cept and numerical method of edge unit were adopted to conduct the calculations of timbering pa-rametcrs of stope. The timbering paramters of lane were determined according to timbering engi-neering empirical formula. The test results of timbering were discussed.
