GNSS CORS networks for coal mine disaster .

Conventional coal mining surveying/positioning and monitoring techniques are both time-consuming and costly. Hence, monitoring is usually constrained to localized areas, and there is no way to monitor any regional subsidence/deformation induced by underground mining.

Monitoring environmental impacts of surface .

Abstract Coal mining generates a number of significant environmental impacts. Due to its synoptic coverage and repetitive data acquisition capabilities, remote sensing has been extensively used to monitor effects of surface mining. Availability of low cost and high resolution data in recent years has focused increased attention on the use of satellite data for monitoring surface mining activity.

Other mines may monitor temperature (often wet and dry bulb) as a matter of course even though there is no problem. At those mines where temperature is a problem, it is usual to measure "effective temperature" which takes air velocity into account as well as wet and dry bulb temperatures, and work periods are shortened if the effective temperature is above a set limit.
