On the No.3 of 'CHINA COAL' 1995, an article under the title of 'Concept and Practice about Large-sized Coal Mine Development by District' was published. In that particular article, the author only dealt briefly with the service scopes of large-sized coal mine development by district. Five years after that, the same author presents a detailed discussion about the matter and proposes that in case of low gas mine when the scope of service is located around the up-hill and down-hill areas with gas density <5, the scope of service should be 7.4 - 12.8km2 and in case the gas density is <10 and >5,the scope of service should be 6.5 - 6.8km2
