非充分采动条件下地表移动概率积分法预测

Prediction of Surface Movement by Probability Integration Method under Condition oof Insufficient Mining

为了研究采动条件下地表的移动规律,基于概率积分法构建了充分采动和非充分采动工作面的地表移动预测模型。通过在非充分采动工作面设置地表移动观测站,并据此对该非充分采动工作面的地表移动进行了现场实测,表明其非充分采动地表移动预测模型的最大移动预测值与移动规律,与实测结果相符。因此,所建立的非充分采动条件下综采工作面倾向和走向地表移动积分法预测模型,可以用于该矿或其他矿井类似工作面的地表移动预测。

In order to study the law of surface movement under mining condition,the prediction model of fully active and insufficient working face is constructed based on the probability integral method.Based on the field observation of the surface movement in the face,the maximum predicted value and movement law of the surface movement prediction model are consistent with the measured results.Therefore,the established prediction model of fully mechanized mining face tendency and moving surface movement under insufficient mining conditions can be used for the surface movement prediction of similar working faces in the mine or other mines.
