| Abstract: | On the basis of analysis of the 5 underlying roadways,which were bestrided by No 4403 isolated fully mechanized mining face with sublevel caving in Dongtan Coalmine,the influence factors and evaluation method of the over extraction roadway stability are discussed in this paper;the structure theory and control principles of the roadway's internal and external layer strata are also presented in it.It can provide basis for controlling additional roadway deformation efficiently and ensuring the regular production of coalface. |
