摘　　要：基于概率积分法的基本原理,讨论了开采沉陷预计计算的任意形状工作面计算坐标系确定方法。根据趋势面分析原理,计算出工作面走向和倾向的方位角,按照开采沉陷学原理确定出工作面各点的拐点偏移距,运用坐标转换方法,确定了任意形状工作面的计算坐标系和实际计算边界。最后运用VC++编程语言实现了相关功能算法,并以实际开采工作面为例,对设计的算法进行了验证。结果表明:提出的方法及算法设计符合实际,实现了任意形状工作面计算坐标系的自动确定。Based on the principle of probability integral method, determination methods of calculating coordinate system for arbitrary shape working face in mining subsidence prediction were discussed. The trend surface analysis method was used to calculate the azimuth angles of the strike and dip directions of the working face. The inflection point displacement of each point on the working face was determined according to the principle of mining subsidence. Combined with the coordinate transformation, computational coordinate and the actual calculating boundary for arbitrary shape working face were also determined. At last, re lated function algorithm was realized by applying VC＋ -t- programming language. The actual working faces in a mining area were taken as an example to verify the designed algorithm. The results showed that the suggested methods and algorithm design were in ling with the fact, and the automatic determination of calculating coordinate system for arbitrary shape working face was realized.
