Iterative algorithm of boundary air leakage in venting laneway along goaf

JI Chuanren1,LI Zongxiang1,LI Jianxin1(College of Vocational,Liaoning Technical University,Fuxin 123000,China)  
It is put forward that the boundary conditions in the laneway along goaf boundary(or working face) is treated with iterative method,and the iterative format and computing method is presented,in order to improve the finite element computing precision of goaf air leakage flow pattern.The concept of working face air leakage ratio is presented against the side air leakage of working face.With the calculated case,it is approved theoretically that the wind pressure distribution(boundary condition of No.1) along the air leakage laneway is non linear,and it is presented that when the air leakage flux proportion in the whole air inlet flux is not very large,the wind pressure distribution of working face is almost linear basically,and the speed of iteration convergence is relative to the air leakage flux.
