Due to the particularity in coal mine production, mine accidents some time occur in countries all over the world, which result in large casualties and economic losses. As equipment that can provides the miners with an emergency shelter when the coal mine accidents occur, the under ground coal mine refuge chamber is paid more and more attention by coal mine enterprises, and the application of the refuge chamber is increasingly widespread. The general functions, the classification, and the successful applications of the underground coal mine refuge chamber are illustrated first, and the research significance on the tmderground coal mine refuge chamber is stated. Following, the development status quo at home and abroad for the refuge chamber is introduced. Then, the implementation methods for the key functions of the underground coal mine refuge chamber are demonstrated. Finally, the prospect for the development of the underground coal mine refuge chamber is stated.展开更多

This paper provides an estimation model of capital loss in agriculture and gives some explanation in marginal approach. With an eye to a balanced and sustainable economy development, it is high time for government to do something for it.展开更多

In the author＇s opinion, this provision has some conflicts with the accounting information quality requirements which require reliability, relevance, comparability, and caution. This paper mainly analyzes the contradictions by comparing the provision with the requirements and putting forward relevant solutions. In the end, this paper has drawn the conclusion that the loss of the long-term asset impairment shall be allowed to switch back with certain conditions.展开更多

Scientists believe that because of sea level rise coastal zone of Bangladesh has already experienced noticeable impacts especially in terms of area of inundation and erosion, saline intrusion, loss of soil and land, loss of crop production in addition to migration of people from vulnerable areas. The loss of land mass and degradation of soil and land resources will adversely affect national food production and thereby food security. Sea level rise impacts are really high for Bangladesh, though the country plays insignificant role in green house gas emission. Development and implementation of adaptation policies and taking initiatives to realize those policies are the right ways to respond to sea level rise impacts in Bangladesh.展开更多
