摘　　要：为了提高煤炭资源回收率,延长矿井服务年限,毛郢孜煤矿在矿井深部采用倾向条带开采村庄保护煤柱,并专门设置了地表移动观测站,进行了多次观测。通过对观测资料的整理、分析,获得了该区条件下倾向条带开采时的地表移动变形规律,并求取了概率积分法预计参数,研究成果对今后皖北矿区及其它类似条件建筑物下安全采煤提供了科学依据。In order to increase the extraction rate of coal resources and extend the service year, Meiyinzi coal mine ruined village protection pillars by using partial extraction along the dip in deepth, established special ground movement observation stations and conducted the observation for many times. Through sorting out and analyzing the observation data, ground movement deformation law when using partial extraction a- long the dip in this area has been obtainted, and prediction paramaters of probability integration method have been calculated. These research results will provide scientific evidence for safe mining under buildings in mines of northern Anhui province and some other mines with similar mining condition.
