摘要裂隙岩体环境下巷道轴线走向优化选择对巷道的安全开挖和长期使用具有重要意义，但现有研究存在代表性结构面组选择和评价指标不够科学两方面的不足。以铜坑矿92号矿体4个裂隙岩体试验区巷道为工程背景，充分利用一般块体理论GeneralBlock程序和关键块体理论Unwedge程序的各自优点，已解决代表性结构面组选择问题，以更符合工程实际的直接掉落块体数目和最小安全系数为块体稳定性评价指标，对复杂裂隙岩体环境下的巷道轴线走向优化进行系统研究。结果表明：利用所研发技术，能够快速确定出1#，2#，3#和4#裂隙岩体试验区巷道轴线最优走向分别为35°，108°，37°和32°。研究成果可为其他复杂岩体环境下巷道轴线走向优化确定提供参考。

Abstract：Optimization selection of the axis strike of roadway under the environment of fractured rock mass is important to the safety of the excavation and the long-term use of roadway，but there are two short coming in existing studies，i.e. the representative structural plane group selection and evaluation indicators is not scientific. Taking the roadways under 4 fractured rock test areas of the ore body No.92 in Tongkeng mine as engineering background，through making full use of the respective advantages of GeneralBlock procedures developed by the general block theory and Unwedge code developed by the key block theory，the selection problem of the representative structural plane group was solved and the number of direct falling block body and the minimum safety factor in line with the actual engineering was used as the block stability evaluation indicator. Thus the study of the optimization for the axis strike of roadway under complicated fractured rock mass was carried out. The results show that the techniques developed could determine quickly the test area #1，#2，#3 and #4 optimal roadway axis strike 35°，108°，37° and 32° respectively. The study results can provide reference for the optimization of the roadway axis strike in other complex fractured rock mass.

Key words： mining engineering fractured rock mass roadway axis strike optimization block theory
