断层型态方程及在构造分析中的应用

Application of the Fault State Equation in Mine Structure Analysis

断层构造是影响矿山生产和安全的主要地质因素之一,为了井下现场快速、准确地定型与鉴定断层,指导采掘巷道布置,应用构造地质学基本原理和数学方法,从断层的空间关系出发,分析断层各几何要素之间的关系,得出断层型态方程,并讨论其在断层型态分类和定型鉴定中的应用。据断层型态方程所做的断层型态分类,能更加清楚地表达断层要素之间的几何关系,反映自然界断层的基本类型;利用易于观测的、与断层型态类型相关的宏观特征来定型鉴定断层,能够方便、快速、准确地在现场解决断层构造问题,及时指导生产。

Fault structure is one of the main geological factors influencing coal mining. In order to rapidly and accurately form and identify the fault at underground field to seek the location of tunnels, the paper proposes a state equation for faults which is deduced from fault spatial geometry relation and mathematical analysis using the basic principle of structural geology and the mathematical means, and discuses its application. According to the fault classification by the state equation, the geometry relation among faults can be clearly described, showing the basic fault types in nature. Using the macrocharacteristics that is easy to observe and related to the states to identify the faults can rapidly and accurately solve some problems on the fault structures to guide production in time.
