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。
Coal seam thickness changes directly related to coal mine design and mining, affecting the deployment of mining and production planning arrangements. The site of coal thickness variation is usually also an anomalous area of gas accumulation. Therefore, accurately forecasting coal thickness is a major technical issue that relates to the production and safety of coal mines. Based on the analysis of different characteristics of different forecasting methods and comparative evaluation of appropriateness, the article puts forward the comprehensive forecasting criterion and establishes a relatively perfect coal thickness comprehensive forecasting system, which provides technical guidance for the reasonable forecast of coal thickness.
