摘　　要：村庄下煤炭资源的开采引起的地表变形会导致居民房屋的损坏,为了实现在地表建筑物损坏最小化的条件下保证出煤量的最大化,就需要统筹规划煤炭开采接续方案的设计。通过建立出煤量与地表建筑物损坏程度的梯形模糊数判断矩阵,计算出不同属性评价指标的权重,通过AHPTOPSIS对备选方案进行优劣度的排序,最终得到了最理想的接续方案。以龙家堡煤矿村庄开采接续方案优选为例,确定了最优备选方案,为同类条件下的煤炭开采提供参考。Surface deformation caused by mining of coal mine under village may lead to damage of residential hou- ses. To realize the maximization of coal production under minimization of damage to buildings on surface, overall arrangement of continuous coordinate mining plan design is necessary. This paper established a trapezoidal fuzzy number judgment matrix of coal production and damage degree of buildings in surface, calculated the weights of dif- ferent attribute assessment indices, conducted the good - bad sequencing of selected plan, and finally, obtained the optimal continuous coordinate mining plan. Taking the optimal selection of the continuous coordinate mining plan of Longjiabao coal mine village as an example, this study determined the optimal selected plan. This study may give a reference to coal mining under villages with similar condition.
