Research and application of key technologies in coal mine drilling management system

In the water exploration and drainage and gas drainage control of coal mines,the "one drilling,one video" system has problems such as inconvenient relocation of cameras and lack of remote monitoring and inspection means for drilling. In response to these problems,the long-distance transmission technology based on cables,as well as the automatic identification and counting technology of drill rods based on AI video analysis were studied. Starting from the process and management requirements of coal mine drilling operations, and combining the application pain points of drilling personnel and managers, a coal mine drilling management system was developed,providing users with functions such as real-time video monitoring,monitoring screen adjustment,basic information management,drilling business management,video query,ledger and report management,two-way voice intercom, and intelligent auxiliary drilling verification, realizing the full process information management of drilling operations. Experiments and practical applications show that the system can achieve 2 km long-distance transmission of video images through cables,and the accuracy of automatic recognition and counting of drill rods is greater than 97. 00%.
