Abstract:
The underground coal mine operating environment is harsh, and mine accidents occur frequently. The automation of underground safety and production management is an important technical way for coal mine enterprises to achieve safe operation and improve production efficiency. [1] The mine roadway not only undertakes the transportation channel for daily production, but also the main escape route for the staff in emergency situations. Therefore, the environmental monitoring of the main roadway of the mine is the basis for ensuring production and safety. [2] At present, the monitoring of roadway deformation mainly adopts manual measurement [3]. This method cannot achieve real-time continuous monitoring and early warning purposes. The automatic transmission and long-distance communication functions especially cannot be realized. Therefore, according to the characteristics of roadway deformation and domestic application, an automatic monitoring and early warning system for surrounding rock deformation of underground mine roadway was developed. The monitoring system collects monitoring data through a series of sensors and passes the microprocessor and RS485 bus. When a dangerous situation is found, the computer will send an AT command to the GPRS (General Packet Radio Service) module according to the set procedure. After receiving the command, the GPRS module will send an alarm message to the set mobile phone. The monitoring system accomplishes the continuous real-time monitoring of the deformation speed of the surrounding rock of the roadway. The data transmission distance is long, the operation is simple, and the single monitoring station is small in size and light in weight, which is particularly suitable for deformation monitoring of various mine roadway projects.
