以贵州六枝特区兴旺煤矿地表塌陷为例,采用概率积分法作为地表移动及变形预测的模式,选取下沉系数、主要影响角、主要影响半径和水平移动系数为地表移动参数,计算得出井田开采后地表最大下沉值为1425.3mm,影响面积约1.85km^2。并比较说明除移动参数外各类煤柱的留设也是其中需要考虑的因素。
以貴州六枝特區興旺煤礦地錶塌陷為例,採用概率積分法作為地錶移動及變形預測的模式,選取下沉繫數、主要影響角、主要影響半徑和水平移動繫數為地錶移動參數,計算得齣井田開採後地錶最大下沉值為1425.3mm,影響麵積約1.85km^2。併比較說明除移動參數外各類煤柱的留設也是其中需要攷慮的因素。

Setting surface subsidence in Xingwang coal mine in Liuzhi area in Guizhou province as an exam- ple, by using probability integral method as surface movement and deformation of a predictable pattern, selecting the sinking coefficient, impact angle, main radius of influence and level of mobility coefficient for the surface movement parameters, maximum sinking value after the coal mining is 425.3 mm, and the influencing square is about 1.85km2. In addition to the movement parameters, various types of coal pillars have also been considered as an influencing factor.
