| The complex hydrogeological conditions and production environment of coal mines in our country make rescue work very difficult when water disasters occur,and the occurrence of coal mine water disasters is difficult to accurately predict and has the characteristics of suddenness.Most coal production enterprises focus on rescue and follow the existing The emergency response plan allocates various disaster relief resources to coordinate and direct all disaster relief entities to carry out water disaster rescue,and the rescue work is carried out through the prepared emergency response plan.This management mode often ignores the role of early warning management,which makes it impossible to identify and promptly identify and respond to crisis warning signals.Prevent possible water disasters and prevent them before they happen.At present,the overall level of my country’s coal mine flood prevention and control work,basic theories,technical equipment,monitoring and early warning,prevention and control methods,etc.,needs to be improved.In order to better manage the work safety of coal mines in our country,we have begun to engage in mid-and post-event management,and change to the pre-management of early warning and forecasting.However,water inrush warning requires a certain amount of advancement.Not only real-time,but also a certain basis for forecasting can be used for early warning.Otherwise,if It is too late to give an early warning when water inrush is detected.There are many factors that affect coal mine water hazards,and the geological mining conditions are ever-changing.The selection and research of important indicators for coal mine early warning needs to be further improved,and higher requirements are put forward for the real-time and rapidness of information,which only rely on conventional hydrology.Geological observations are no longer sufficient.It is difficult to accurately judge the existing problems and hidden dangers based on one or a few indicators for early warning of water hazards.Therefore,this paper conducts an in-depth study on the water hazard early warning index system of Tingnan Coal Mine to achieve the purpose of water hazard prediction and early warning.The main research results are as follows:1.Analyze and research the geological and hydrogeological conditions of the Tingnan mining area,grasp the basic situation of the study area,the occurrence of various water hazards and the construction of monitoring and early warning conditions,and comprehensively grasp the ledger data,basic maps and regional geology owned by the mining area Report,Tingnan hydrogeological supplementary exploration report,etc.,summarize the characteristics of regional hydrogeological conditions.2.In view of the complex hydrogeological types of coal mines in Tingnan and the increasingly prominent water hazards,research and analyze the sources of water hazards in Tingnan Coal Mine and their main disaster-causing factors,sort out and improve the collected data of influencing factors,and make full use of the existing data of Tingnan Mine Data and monitoring equipment to achieve information integration.3.In accordance with the basic principles of the establishment of the indicator system,data collection methods,data characteristics,and degree of influence,establish water hazard early warning indicators,and jointly establish a water hazard early warning indicator system in Tingnan Mine,and conduct indicator research,analysis and analysis on each refined indicator The relevance of coal mine floods.4.Use appropriate prediction algorithm models for dynamic indicators,use LSTM long-term short-term memory network time series model,ARIMA model,SVM model,GIS spatial analysis model,Wintersgar index model and other methods for data prediction to ensure the fitting of prediction results Good performance,smaller errors,and more accurate values;static indicators are analyzed and quantified through safety checklists;relevant indicators are analyzed through industry regulations and judgment standards,and the research results are closer to scientific and practical,so that the indicators The research provides reference value for advanced prediction and early warning.5.Using the analytic hierarchy process and the use of fuzzy mathematics,establish a single indicator and multiple indicator fusion early warning model based on the Tingnan Mine’s water hazard early warning index system to achieve single-factor and multi-factor early warning,and provide a reference for the Tingnan Mine’s water hazard prevention and control work.Predict and prevent hidden water hazards to provide reliable guarantee.This research paper has 45 figure,16 table,and 67 reference. |
