Pan Qi-dong, Ruixin Zhang, Duan Dong-sheng, Gang Sun · 2009
Today the serious casualties of Chinese coal mines happened frequently and caused great casualties and property losses. This situation is extremely associated with scarcity of advanced emergency management(EM) methods for emergences forecast & precaution and decision-making. Data integration of coal mine safety production (CMSP) system is the foundation of solving above problems. According to the multi-source and heterogeneous features of CMSP System, this paper analyzes several ways of data integrating, and concludes that the combination of data warehouse and middleware (named data-center) can solve the problems effectively. On this basis, a meta-framework model for coal mine EM system is established, and the data integration system for coal mine emergency decision-making is designed. At last, the conversion problem of heterogeneous-source data is analyzed.
