【摘要】 为进一步实现煤矿工作面自动化、智能化、便利化预警,提高煤矿智能系统的人机交互能力,达到实时预警、精准预警目的,基于地质信息,通过计算机建模方法,根据已有知识和经验建立物理模型。首先分析和设计煤矿工作面超前预警系统,通过物理仿真进行建模。在煤矿掘进期间,根据当前开采线位置,对工作面周边危险源进行超前预警判断及风险评估,动态预测前方范围内存在的危险源情况,提高了开采的安全性。对断层、陷落柱、积水区、煤柱、采空区等危险源进行动态超前预警。判断并显示当前虚拟区域内危险源的信息及距离工作面开采位置范围的风险评估。超前预警系统平台显示实时检测数据变化趋势、推进情况及决策信息详细内容,从而实现对煤矿工作面信息化、智能化、无人化的超前预警。更多还原

【Abstract】 In order to further realize the automatic,intelligent and convenient early warning of coal mine working face,improve the human-computer interaction ability of coal mine intelligent system,and achieve the purpose of real-time early warning and accurate early warning. Based on the geological information,the physical model is established by computer modeling method according to the existing knowledge and experience. Firstly,the advance warning system of coal mine working face is analyzed and designed,and the model is built through physical simulation. During the excavation of coal mine,according to the position of the current mining line,advance warning judgment and risk assessment of the hazard sources around the working face can be carried out,and the situation of the hazard sources existing in the front range can be dynamically predicted,which improves the safety of mining. To fault,collapse column,water area,coal pillar,goaf and other dangerous sources for dynamic early warning. Determine and display the information of hazard sources in the current virtual area and the risk assessment of the range from the mining position of the working face. The advanced warning system platform displays the change trend of real-time detection data,the detailed contents of the advancement situation and decisionmaking information,so as to realize the advanced warning of the coal mine working face information,intelligence and unmanned.更多还原
