Research On The Automation Control System Of Zhaogu Coal Mine Drainage

The drainage system of coal mine, as a part of the work of coal mining, timely and efficient elimination of the various water of mining process, directly determines the production of coal mine underground mining and the work. Coal mining experience from the staff caretaker on site to the relay remote control. Both need a relatively heavy human consumption. So modern mine drainage systems desperate need of new way to change the traditional control methods to improve production efficiency. Drainage system using PLC for automation control, compliance with requirements of the development of modern coal mine.The system combines the actual drainage of coal Zhaogu mine, uses PLC315-2DP/PN of Siemens series, the CPU itself is integrated Ethernet interface, no additional communication modules needed, based on the actual expansion of the digital modules and analog modules, can work in automatic and manual, used action more quickly and reliably electric valve and sensor instead of the original manual control valves and instrumentation. In the process of operation monitor on the underground water level in real time. Timely and efficient exclude coal mine water, to achieve the purpose of energy efficient, created based on the principle of avoiding peak and trending to vale mathematical model, using matlab to achieve mathematical solution, to achieve maximum energy saving, reduction of coal normal production costs. At the same time the use of advanced control strategies, a reasonable choice pumps and pipes, fully consider the principle of rotation, so that each pump and pipes have been reasonable used, preventing long-term use of a pump and pipes.The system is using the configuration software Intouch screen monitor, using Industrial Ethernet communication, to achieve real-time remote monitoring and control.
