Monitoring and control systems to minimise the influence of mining plants on environment

摘要

Mining carries a great number of noxiousnesses for the environment. In the deep coal mines, there are many hazards in underground workings and on the surface around mining plants. The mine ventilation systems emit to the atmosphere large quantities of air including mine air constituents from which methane, CO or CO_2 have an effect on air pollution around the surface ventilation stations. The noxiousnesses of ventilation stations are equally vital owing to considerable consumption of electric energy and noise making. One of the possible minimisation forms is complex monitoring of ventilation stations with the range of upcast air parameters, reduction in electric energy consumption by the control systems of the fan motors. The scattered monitoring system of ground deformations and damages to industrial objects, apartment buildings and housing estates can be used for observation of mining activity on the surface. Coal preparation plants are the essential sources of environment pollution. It is considered to monitor and control coal quality parameters underground.
