Abstract: Xinjiang province, abundant with coal resource, is the 14th modernized large coal base in China. As it is located in arid and semi-arid area, the exploitation of Xinjiang coal base is trapped into the contraction between large-scale mining of coal resource and protection of highly fragile eco-environment. How to efficiently exploit coal resource in conjunction with eco-environment protection is a great scientific issue in Xinjiang Coal Base. This paper focuses on how to study on the connotations, objectives and features of the adaptation of existing mining technology in thick coal seam, the selectivity of high-efficiency mining technology restricted by environmental capacity, the feasibilities of water-protective mining and backfilling mining and the originality of fully mechanized mining technology in giant-thick coal seam and steep coal seam. The preliminary conception and prospection is presented in order to broaden the concepts on constructing green development of large coal base.

Key words: large Xinjiang coal base, scientific mining, eco-environment protection, high-efficiency mining, green mining
