Mathews稳定性图法在薄矿体开采采场设计中的应用

摘要

正确的采场设计是保证安全开采的必要前提，尤其对于薄矿体的开采，必须建立在详细的岩石地质调查的基础上。以沟里金矿果洛龙洼矿区为工程背景，介绍了Mathews稳定性图法的应用方法和步骤，包括井下节理裂隙调查与分析、水文地质调查与分析、岩石性质调查与分析、理论计算分析等。在此基础上对采场的稳定跨度进行了计算，调查结果还可以为巷道支护、爆破设计提供基础资料。%Proper stope design is essential prerequisite of safety mining , especially of the thin ore body mining which must be based on thorough investigation of geological survey .In the engineering background of Gouli gold ,this paper introduces the method and process of Mathews Stability Graph , including investigation and analysis on under-ground joint crack ,hydrogeology ,rock properties and theoretical calculation analysis and so on .Then based on the re-sults the stability span is calculated .The investigation results could also be the basic data for roadway support and blast design .
