【摘要】 岩石力学性质与测井曲线参数之间具有相关性,可利用单因素及复合因素求取岩石力学弹性参数,为矿井开采技术措施的制定提供参考。结合皖北祁东矿勘探测井曲线分别求取岩石弹性模量、泊松比以及抗拉强度,结果表明:利用测井曲线求得的岩石弹性模量和泊松比与实验室测试值具有一定的比例关系,从而实现了利用测井曲线求取岩石弹性模量和泊松比;同时,根据视电阻率测井曲线、伽马伽马测井曲线和自然伽马测井曲线与岩石抗拉强度的相关性构建复合参数,利用复合参数计算的岩石抗拉强度与实验室测试值具有高度相关性,为巷道支护及工作面回采提供了理论依据。更多还原

【Abstract】 Since logging curve parameters have correlation with rock mechanical properties,rock elastic parameters can be obtained by using single and composite factors to provide reference for mining technology and measures.In this paper rock elastic modulus,Poisson’s ratio and tensile strength were respectively gained on the basis of logging curve in prospecting Qidong mining area in northern Anhui.The results show that there is certain proportional relationship between rock elastic modulus and Poisson’s ratio based on logging curves and measured value in laboratory,thus making it possible to get rock elastic modulus and Poisson’s ratio by using logging curves.Besides,composite parameters can be constructed according to the interrelationship between apparent resistivity logging curve,artificial gamma logging curve,natural gamma logging curve and rock tensile strength,and the rock tensile strength computed by composite parameters is significantly correlated with the laboratory measured value,thus providing theoretical basis for roadway support and face mining.更多还原
