众所周知,对于以影响函数法所确定的地表移动盆地来说,多数情况下并未完全考虑回采工作面线、采区边界以及工作面的残留煤柱对移动盆地的影响。回采边界及残留煤柱正上方的地表点,以目前的计算方法所得到的下沉预计值多数情况下偏大。这样,一方面使下沉盆地在采区边界一侧变陡,而另一方面使煤柱两侧的下沉影响减弱,如图1所示,从而得出错误的估算结果。对于煤柱的影响问题,早在1982年克拉茨曾建议,可将煤柱面积作为有效的下沉单元来考虑,并计 It is well-known that for the surface-moving basins defined by the impact function method, the effect of residual coal pillar on mining face line, mining boundary and working face on moving basin is not fully considered in most cases. Surface subsidence at the mining boundary and residual coal pillar is large in most cases with the subsidence predicted by the current calculation method. In this way, on the one hand, the subsidence basin is steeper on the border of the mining area and on the other hand, the sinking effect on both sides of the coal pillar is weakened, as shown in Figure 1, which leads to erroneous estimation results. As for the impact of coal pillars, Klatz had suggested in 1982 that the coal pillar area could be considered as an effective sinking unit, and the total
