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.

产品说明：该项目的总体目标是通过开发最先进的稳定性绘图系统，将地质力学应力分析、地质绘图和顶板支护设计紧密结合起来，减少地下矿山与地面福尔斯坠落相关的伤亡。 该项目的主要产出将是一个用户友好的软件程序，该软件程序将现场特定的采矿计划、地质和稳定性标准作为输入，并生成一张矿山地图，显示不同采矿区的相对稳定性指数和这些地区的建议支持要求。 本程序中计算的稳定性指数将包括矿山沿着的适当地质影响，以及上覆岩层深度、煤柱设计、相邻煤层、河谷和其他用户定义影响的地质机械应力影响。 该计划中的顶板支护建议将来自目前的NIOSH研究（Mark等人，2001年）的报告。 拟议的软件开发将尽可能合并/修改/增强现有软件（Auto CAD -绘图/矿山绘图、SurvCADD -地质建模和LaModel -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。 一旦软件被创建，该程序将在几个矿山进行现场测试和现场研究。通过这一现场测试过程，可以制定和验证稳定性指数和实际支持要求的各种输入的实际加权系数。 此外，通过与生产矿山合作，可以评估所开发软件的实际应用，并通过实践矿山设计专业人员的输入来增强。 最终，最终的稳定性绘图系统将通过出版物、研讨会和其他适当的演示文稿转移到采矿业。
