煤矿顶板稳定性影响因素分析与评价

Analysis and assessment of factors affecting the stability of coal mine roof

根据顶板自然条件,结合监测的技术因素,建立了煤矿生产中顶板的稳定性状况的评价模型,模型划分为3层,并包含了开采深度、煤层强度、煤层厚度、地质构造等10个影响因素,可为顶板事故的隐患查找、状况评价和事故预警等工作提供理论依据。

According to the geological and mining conditions of coal mine, the assessment model of the roof stability in coal mine production was established. The model was divided into three layers and contains ten factors such as mining depth, coal seam strength, coal seam thickness and geological structure and so on, which can provide theoretical basis for the roof status assessment and accident warning.
