Basic roof slope direction along the face breaking position is affected remain a major factor in the success lane , face end curved triangle blocks for understanding the stability of surrounding rock deformation characteristics for roadside packing Lane provides an important theoretical basis. This paper analyzed results of previous studies based on the use of strata control stope critical layers , masonry beam theory the basic principles and methods affected by mining the lane next to the filling gob rock deformation regularity a systematic analysis , presented with a stability factor K 1 , K 2 to reflect the left lane, when the curved triangle blocks affected by mining under stable conditions , the establishment of reflect the basic characteristics of the four mechanical model that exo- , endo-type , fitted type , inline four kinds . Numerical simulation , physical simulation and field test a variety of research methods such as mechanical model of the general rules of Strata conducted a comprehensive analysis, the results showed that: face end curved triangular pieces breaking in different positions on the left lane rock deformation damage have a greater impact ; filling strength is small, the largest endo- rock deformation , exo- Min ; filling greater intensity , the yield with regional variation is not great, but other than that embedded type largest endo- Min , and on the roadway to help stress field range is also larger . Also analyzed the East Mine 12,101 basic roof face end breaking position , elaborated stope structure types , departments and regions to establish a curved triangular structure with filling structure to deal with the relationship between the proposed 12,101 face beside Lane filling left lane layout scheme . The research results have been in East 12101 Face coal roadway layout has been verified , field application and achieved good economic benefits.
