地表的水平变形和垂直变形,都是做为最大下沉函数来计算的η_(max)=q_omcosαN_1N_2 (1) 式中η_(max)—最大下沉,米; q_o—在水平埋藏和充分采动条件下,由实地观测确定的相对最大下沉值(也叫下沉系数); m—采出厚度,米; α—煤层倾角,度; The horizontal and vertical deformation of the surface are calculated as the maximum sinking function η_max = q_omcosαN_1N_2 (1) Where η_ (max) - the maximum sinkage, m; q_o - buried in the horizontal and full recovery (Also called sinking coefficient) determined by field observation; m - thickness of mining coal, m; inclination of coal seam α, degree;
