The method comprises the following steps that according to collected point cloud data, a map of a roadway is generated by utilizing an SLAM algorithm, an LSTM model is constructed and trained according to the collected gas concentration data, long-short-period prediction of the gas concentration is realized by constructing a prediction model of the gas concentration, a path of the equipment can be automatically planned by generating the map of the roadway, the underground GPS-equipment-free autonomous navigation and mapping functions are achieved, underground gas intelligent acquisition, cloud intelligent storage and intelligent analysis and prediction are realized, and a guarantee is provided for safe, green and efficient mining of a deep coal mine.

Description

technical field [0001] The invention belongs to the technical field of mine intelligent safety monitoring, and in particular relates to a roadway gas cloud intelligent monitoring device and method. Background technique [0002] my country is "poor in oil, low in gas, and relatively rich in coal", and coal still occupies a large proportion of my country's basic energy. With the increase of mine mining depth, more than 50% of the current production mines are coal and gas outburst and high gas mines, which are prone to coal and gas outburst, gas explosion and gas concentration exceeding the limit during the production process. Large-scale damage and low-prediction safety accidents are major safety problems that need to be solved urgently in coal mine production. The main hazard caused by the gas in the working face and the roadway is the gas explosion. The high-pressure and high-temperature airflow generated by the gas explosion will spread rapidly along the existing roadway, ...

Problems solved by technology

[0003] Mine gas concentration monitoring is especially important to the prevention and control of gas disasters. Traditional monitoring mainly relies on manually arranging a large number of measuring points and performing multiple measurements on each measuring point. The on-site construction process is cumbersome, the monitoring workload increases, and the data processing time is long and the accuracy is low. , and the existing monitoring equipment has limitations such as high cost, poor anti-interference ability, cumbersome operation, high technical requirements, and few measurement data. Accurate, fast, intelligent and efficient monitoring of roadway gas concentration
