Integrated Stability Mapping System for Mines

描述：该项目的总体目标是通过开发一种最先进的稳定性测绘系统，将地球机械应力分析、地质测绘和顶板支撑设计紧密结合起来，减少与地下矿山地面坠落相关的伤害和死亡。这个项目的主要产出将是一个用户友好的软件程序，它以特定地点的采矿计划、地质和稳定性标准作为输入，并制作一幅矿区地图，显示不同矿区的相对稳定性指数和这些矿区的建议支助要求。本方案计算的稳定性指标将包括矿山适当的地质影响，以及覆盖层深度、矿柱设计、相邻煤层、溪谷和其他用户自定义影响的地力学应力效应。该计划中的屋顶支撑建议将来自目前NIOSH的研究（Mark等人，2001年）。拟议的软件开发将尽可能地结合/修改/增强现有的软件（Auto CAD -制图/矿山测绘，SurvCADD -地质建模和lammodel -矿山应力分析），以加快开发速度并提供矿山设计工程师已经熟悉的软件。

DESCRIPTION: The overall objective of this project is to reduce the injuries and fatalities associated with ground falls in underground mines by developing a state-of-the-art stability mapping system which tightly integrates geo-mechanical stress analysis, geological mapping and roof support design. The primary output of this project will be a user-friendly software program which takes the site-specific mining plan, geology, and stability criteria as input and produces a map of the mine showing the relative stability index of the different mining areas and the recommended support requirements for those areas. The calculated stability index in this program will include the appropriate geologic influences at the mine along with the geo-mechanical stress effects from overburden depth, pillar design, adjacent seams, stream valleys and other user-defined influences. The roof support recommendations in the program will be derived from present NIOSH research (Mark et al., 2001). The proposed software development will incorporate/modify/enhance present software (Auto CAD - drafting/mine mapping, SurvCADD - geologic modeling, and LaModel - mine stress analysis) as much as possible in order to speed the development and provide software that is already familiar to the mine design engineer. Once the software is created, the program will be field tested and validated with field studies at a couple of mines. Through this field-testing process, practical weighting factors for the various inputs to the stability index and practical support requirements can be developed and validated. Also, by working with producing mines, the practical application of the developed software can be evaluated and enhanced with input from practicing mine design professionals. Ultimately, the final stability mapping system will be transferred to the mining industry through publication, workshops, and other presentations as appropriate.
