Based on the situation analysis of farmland destruction in mining area, three ways for farmland protection were proposed. In order to improve the feasibility of this technology, the limited filling materials should be used to increase resources recovery ratio, and then the surplus materials could be backfilled into goaf. An index, namely farmland conservation ability, was put forward to optimize the ways for farmland conservation. At last, the Wanbei coal mine was taken as a case for farmland conservation. It was shown that 3240 t dull coal was substituted and 52 hm2 farmland was conserved by solid backfilling mining in this coal mine.展开更多

To keep abreast of the farmland water conservancy and various related environmental parameters,we can use the external sensors to acquire real-time data,employ the computer technology,networking and communication technology,database technology,geographic information system( GIS) technology,component technology and other advanced modern information technologies combined with the automated water conservancy technology,in order to build an accurate,efficient,fast,comprehensive,standardized decision support system integrating farmland water conservancy and irrigation information collection,transmission,storage,management and analysis. In this paper,we give details about the overall framework design of farmland water conservancy and irrigation management system based on GIS,information collection and data input,and information processing and data output,to provide a reference for the digital water conservancy construction in China.展开更多
