technical field

The invention relates to a coal mine early warning method, in particular to a coal mine hazard source early warning method.

Background technique

In high-risk industries such as coal mines, hazards refer to the source or state that may cause personal injury or disease, property damage, or damage to the working environment. Hidden dangers are factors that are unstable in certain conditions, things and events and affect the safety and interests of individuals or others. The generation of dangerous sources may lead to hidden dangers and even accidents. Monitoring and early warning of dangerous sources can avoid hidden dangers and accidents. Therefore, early warning of dangerous sources in coal mines plays an important role in the safe production of coal mines.

Map is the most intuitive and vivid visual carrier of spatial information, and the particularity of spatial data makes map-based interactive visualization a special way of information visualization. Hazard sources and hidden dangers always exist in a certain geographical location, that is, the data sets of hazard sources and hidden dangers containing address information have geographical structure components. Hazard source map visualization displays related fields (such as hazard source content, responsible person, rectification period, etc.) on a spatial primary key as graphic elements on the visual map. Establishing a direct relationship between coal mine hazard sources and people and things in a virtual and visualized environment, predicting and avoiding possible hidden dangers and accidents in advance, will effectively promote the safe production of coal mines.

At present, various mine digital systems about hidden dangers and danger sources are widely used in coal mines. The danger source early warning system uses mature computer, network, visualization, database and other technologies to store the basic information in the database in advance through hazard identification and early warning. Data, in the process of hazard source monitoring, through the association between the hazard source and the coal mine electronic mine map, the broadcast and early warning of the hazard source are realized in multiple visual terminals such as the coal mine electronic map and the large screen at the wellhead. However, these operating methods are artificially The operation ability is very strong. For the timely discovery of underground hazard information, it may not be timely entered and reviewed in the system due to actual underground operations or long distances. In addition, there may be some major impacts on coal mine production. Information on dangerous sources cannot be discovered by the staff in a timely and effective manner, which will also affect the normal production of the coal mine.
