瓦斯地质在突出预警指标体系建立中的作用研究

Study on effect of gas geology in the establishment of gas outburst warning index system

预警指标体系研究是整个预警系统项目实施的前提,为实现矿井煤与瓦斯突出综合、智能、超前、动态预警提供技术基础。整个预警系统指标体系框架主要包括瓦斯地质、采掘影响、日常预测、瓦斯涌出、矿山压力、防突措施6个方面。地质构造是控制突出的主导地质因素,构造软煤厚度和煤层瓦斯含量是突出区域预测主要瓦斯地质指标。地质构造通过控制瓦斯赋存、煤体结构类型和构造应力来控制突出。此次主要以瓦斯地质为核心,研究瓦斯地质在预警指标体系建立中的作用,对矿井预警指标体系的建立具有指导作用。

Research on early warning indicator system is a prerequisite for the entire project implementation of early warning systems, provides a technical basis for coal and gas outburst warning synthetically,intelligently,advance and dynamically.The entire warning sys-tem indicator framework including gas geology,mining impact,daily forecast,gas emission,underground pressure,preventing gas out-burst measures.Geological structure is the dominant factor of controlling prominent,tectonic soft coal seam thickness and gas content are the major geological indicators of gas outburst regional prediction. Geological structure control prominent by controlling the gas occur-rence,coal structure and type of tectonic stress.Gas geology as the core,this article study on the effect of Gas Geology in early warning indicator system,has a guiding role in the establishment of mine warning index system.
