冲击地压机理要素分析与评价

本文提出了冲击地压的能量特征和机理要素，初步建立了巷道冲击地压机理评价指标与体系(简称"3+4"指标体系)，体系的主准则层为冲击地压的能量释放特征指标和机理要素指标，次准则层为能量释放突然性、瞬间性、集中性以及形成要素、关键要素、假设条件、普遍规律性。采用层次分析法计算了各准则层的权重，提出了综合评价结果的计算方法和分级标准。按照建立的冲击地压机理评价指标体系对蝶型冲击地压机理进行评价，评价结果为"优秀"。研究结果可用于评价现有冲击地压机理，同时为冲击地压机理的后续研究指明了方向。

Analysis and evaluation of essential factors for rock burst mechanism

This paper puts forward the energy characteristics and mechanism elements of rock burst, and preliminarily establishes the evaluation index and system of roadway rock burst mechanism ("3 + 4" index system).The main criterion layer of the system is the energy release characteristic index of rock burst and the key element index of rock burst mechanism.The secondary criterion layer is sudden energy release, instantaneous energy release, concentrate energy release, and forming element, key element, hypothesis condition and universal regularity.The weight of each criterion layer is calculated by analytic hierarchy process method.The calculation method and classification standard of comprehensive evaluation results are put forward.According to the established evaluation index system of rock burst mechanism, the butterfly rock burst mechanism is evaluated, and the evaluation result is "excellent". The research results can be used to evaluate the existing rock burst mechanism, and point out the direction for the follow-up research of rock burst mechanism.
