In this paper,a theoretical method of monitoring the working face floor stability by angular displacement is used to provide a theoretical basis for the on-site monitoring.
从理论上运用角位移方法监控工作面底板稳定性的原理和可行性,为现场监控工作做理论基础。
6) coal roof stability
煤层顶板稳定性
1.
Coal roof faulted structure is most important factor to influence coal roof stability.
煤层顶板断裂构造是煤层顶板稳定性影响因素中最重要的因素,以兖州煤田鲍店煤矿为例,分析了兖州煤田顶板断裂构造特点,探讨其对煤层顶板稳定性影响,分析了小断裂对煤层顶板的稳定性影响,断裂密集区的煤层顶板最易垮落,特别是交错断裂区更易产生顶板垮落式冒顶。
2.
3 coal roof stability is mainly influenced by roof structure and lithology,therefore quantizing the two factors first,through 3D seismic prospecting comprehensive interpretation and wave impedance inversion interpretation,then normalized wave impedance data,made the impedance data and quantized structure data .
考虑3煤层顶板稳定性主要受其顶板的构造信息和岩性信息影响,因此首先依据三维地震勘探综合解释成果及波阻抗反演解释成果对二者进行定量化,然后对波阻抗数据进行归一化处理,使得波阻抗数据和量化后的构造数据具有相同的变化范围及等量贡献。
