With the developmentoftechnology, shortwall mining has become safer, more mechanized and more efficient, and will have much higher yield and recovery ratio. The equipment, safety, single productivity, resource recycling rate ofitsworking surface have been greatly improved. Besides, mechanization of the process, such as coal dropping, conveying and supporting can be realized. This technology, being an important supplement for longwall miningtechnology,iscalledmodernshortwallmechanical loopingmining technology. Therefore, study on the ofshortwall mininghasimportant theoretical and realistic significance for reducing or releasing large quantity scraps, residual pillars and the undergoing“Three Unders” coal mining. Focusingonthe problemofcoal scraps, relic pillars, and low resource recycling rate, through analyzing coal resource in our mine, this paper studies the necessity of shortwall mining , analyzes the parameter of ground surfaceshiftand distortion educed on the basis of the special geological conditionsofourmine and the results of rock movement observation station, and demonstrates the significanceofstudying shortwall mining on reducing mining damage. Meanwhile, basingonthe shortwall mining experience of mines with advanced technology, this paper puts forward a sustainable shortwall mining suitable for longwall and shortwall combination , which uses both thorough mining and non-thorough miningand can realizethe sustainable developmentofmines and the constructionofeconomical society. Furthermore, this paper devolve into the “Three Unders” mining in order to provide a scientific mining to reduce mining damage, and to provide reference and basis for developing a shortwall mining suitable for Huxi Mine whichisa jointed mine of Daizhuang mine.
