【摘要】 煤层厚度变化直接关系煤矿设计与开采,影响采掘部署和生产计划的安排实施。煤厚变化部位通常也是瓦斯聚集异常区,因此,准确预报煤厚是关系到煤矿生产与安全的重大技术问题。文章通过不同预测方法差异特点分析及适宜性对比评价,提出综合预测准则,并建立较为完善的煤厚综合预测方法体系,为煤厚合理预测提供技术指导。更多还原

【Abstract】 Coal seam thickness change has a direct relationship with coal mine design and exploitation.Moreover,it impacts mining deployment and implementation of production planning.The parts of coal seam thickness change are also usually at the anomaly area of gas aggregation.Consequently,predicting coal seam thickness accurately is a significant technical problems in coal mine production and safety.The principle of comprehensive prediction is proposed by the analysis of difference of various forecast methods and comparative evaluation of suitability in this paper.The system of comprehensive prediction is established for the purpose of providing technical guidance for forecasting coal seam thickness reasonably.更多还原
