Research On Division Of Gas Geological Units And Database Development In Kailuan Mining Area

Gas has always been a huge safety hazard during coal mining,Safety accidents caused by gas often occur,causing major casualties and corporate losses.The traditional gas information management methods can no longer meet the needs of modern safety production.In order to better strengthen the management of gas parameters in kailuan mining area,to understand the law of gas occurrence and the characteristics of gas zoning,the geological structure of the Kailuan mining area and the coal seam and coal quality were studied,combining relevant geological data to analyze gas occurrence characteristics.The results show that the gas in kailuan mining area is mainly affected by regional geological structure,burial depth and magmatic activity.On the basis of summarizing the predecessor's basis for the division of gas geological units,combined with the geological conditions of the Kailuan mining area,the Fangezhuang mine,Linxi mine,Lujiayu mine,Donghuanyu mine,Qianjiaying mine and Tangshan mine has been divided into gas geological units.Based on the actual production needs of Kailuan Coal Mine,a gas basic parameter management system based on MYSQL database was designed and developed,which made the quantity and variety of frequent gas data management more standardized and complete,and used the characteristics of information to make up for the shortage of traditional gas management.Link the gas geological unit division map with the database on the query function interface,by clicking on the corresponding position on the gas geological unit map,you can link to the back-end database,and display the gas parameters at that point,you can more intuitively understand the gas situation in the mining area,easy to query and enter gas data.Through the gas geological unit map,you can intuitively understand the gas distribution characteristics.Click the corresponding position on the gas geological unit map to know the detailed gas parameter information.This makes gas management more accurate and efficient,and plays an important role in guiding safe production in the mining area.Figure 41;Table 7;Reference 51...
