摘　　要：地层移动角参数对巨厚松散层矿井的建筑物保护煤柱尺寸影响很大，经济潜力十分巨大．目前我国绝大多数矿区，均采用一组松散层移动角参数整段设计留设建筑物保护煤柱的方法，该方法有时不尽合理．在淮北矿区巨厚松散层条件下，依据实测资料和土工实验结果，分析了土体性质随埋深的变化特征，论述了按土层埋深和沉积年代分段划分巨厚松散层移动角量参数的两种方法，并给出了淮北矿区相应的参考角量值．The displacement angle of strata has a great bearing on the size of coal pillar for protection of buildings on very thick unconsolidated layers,and has a great economic potentials.So far,only a group of parameters are used in design of coal pillars for protection of surface buildings on a complete section of loose layer in most of coal mines in China.Sometimes,this method is not reasonable.Based on the measured data and test data of soils,variation of soil characteristics with the depth is discussed,and two methods for determining the displacement angle of extra thick unconsolidated layers are discussed,in which the complete unconsolidated layers are divided into sections in terms of depths or depositional age.The corresponding displacement angle parameters are given for Huaibei coalfield for reference.
