生产实践中，受采煤技术、地质条件等因素的影响，所开采的工作面往往是煤层走向或倾向不能同时达到充分采动，因此面临的问题是如何将小工作面开采条件下的概率积分法计算参数换算为充分采动或接近充分采动条件下的计算参数，对于下沉系数的修正又是小工作面概率积分法计算参数的关键所在。通过对比某矿地质条件相似的不同工作面下的计算参数后，表明现有的下沉系数修正规律适用于某矿区。

In production practice,influenced by coal mining technology,geological conditions and other factors,the work-ing face cannot achieve full mining at the same time in coal seam strike or dip. So,the issue faced is how to convert some cal-culation parameters of probability integral method under the condition of small face mining into parameters under full or close to full mining conditions. Also,correction in factor of subsidence is the key to calculate the parameters by small-face probability integration method. After contrast on calculating parameters of different working faces under similar geological conditions,it is indicated that the correction rules of existing subsidence coefficient is applicable to this mining area.
