Abstract: According to the actual production situation of multi-sublevel in mine,the mining method of multi-sublevel and multi-stope is put forward on the basis of the stress arch theory.The specific minging ways of stacked arch is analyzed in detail,the exploration transportation,ventilate,the mine production capactiy,the quantities of construction are discussed.The research results show that the length of the drop shaft and ventilation raise are increased so as to mining the combination sublevel by setting the centralized traffice levels and centralized level of return air,but it contributes to production management of stacked arch mining.The production of stacked arch mining is improved 40％~70％ than the sigle sublevle mining.In addition,the mining method can be formed during the the mining production,so there is no need to increase the mining construction engineering quantity by adopting the stacked arch mining method,and the safety situation of this method is better than the others.

Key words: Stacked arch mining method of muti-sublevel and multi-stope, Stree arch, centralized traffice levels, Combination sublevel, Construction engineering quantity
