The mining practice of a fully-mechanised face with long strike length in a coal/gas outburst-prone area

The number of mining districts and the investments of mine development engineering can be reduced, the mine production costs can be cut and the ''High output and high benefit'' of mining production can be attained by mining fully-mechanised faces with long strike length. This article introduces the process of its design, development and mining, and gives the correlating safety technical measures through the successful mining practice of a working section 2208 m long on strike in a coal-and-gas outburst-prone area in the No.1 mine of Pingdingshan coal Administration. Also the correlation analysis of effective factors and application conditions of the mining method are given with proposals.
