Study on forming a set of equipment of comprehensive light-duty supports for sublevel caving coal mining and its mining technology

First,the light?duty support working?face distribution,the forming set of the equipment and some other programs are described.Then,based on the theoretical analysis and the fieldwork experiments,the mining technology,methods and the parameters are optimized,and a technique model which is suitable for the light?duty supports is established.Thus,a better technological and economy result is obtained.Finally,it states that the middle and small coal mines can adopt the combined mining technology(comprehensive sublevel caving)instead of the blast?winning technology.
