Automatic coal mine disaster monitoring system based spatial information service

China is the largest coal producing country in the world, but its development pattern of coal industry is still at a relatively low level, there are still many problems to be solved in china. Geographical information technology has not fully been utilized in coal disaster prevention and control. It is rare to watch an integrated application of digital mine, and coal warning system based on spatial information is not really set up. This paper explored coal mine safety monitoring based on spatial information service, and discuss present status and existing problems. Automatic coal disaster monitoring based spatial information service is presented. We also go into detail this system and its key issues in this paper.
