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.

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，将地质力学应力分析、地质测绘和顶板支撑设计紧密结合在一起，减少与地下矿山地面坠落相关的伤亡。该项目的主要输出将是一个用户友好的软件程序，该程序将特定地点的采矿计划、地质和稳定性标准作为输入，并生成矿山地图，显示不同矿区的相对稳定性指数和建议的这些区域的支持要求。本程序中计算的稳定性指标将包括适当的矿山地质影响，以及覆岩深度、矿柱设计、邻近煤层、溪谷和其他用户定义的影响所产生的地质机械应力效应。该计划中的屋顶支撑建议将来自目前的NIOSH研究(Mark等人，2001年)。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/矿山制图、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。 一旦创建了软件，该程序将进行现场测试，并通过几个矿山的现场研究进行验证。通过这一现场测试过程，可以为稳定指数和实际支持要求的各种输入制定和验证实用的加权系数。此外，通过与生产矿井合作，开发的软件的实际应用可以通过实践矿井设计专业人员的投入进行评估和增强。最终，最终的稳定性地图系统将通过出版物、研讨会和其他适当的演示传递给采矿业。
