“孤岛”综采放顶煤工作面矿压预测预报

Forecast of Underground Pressure for a Fully-Mechanized Sublevel Caving Face with Four Mined Boundaries

在现场实测的基础上，采用灰色等维拓扑方法对国内首例四面为采空区的“孤岛”综采放顶煤工作面的矿压显现进行了近、中期预测预报，取得了理想的效果，保障了“孤岛”综放工作面的安全开采。

Based on a field measurement, the forecast of strata behaviors for a fully-mechanized sublevel caving face with four mined boundaries, called 'isolated island' face, has been carried out using the method of grey isodimentional topology. The effect is good, ensuring the safe mining of the fully-mechanized sublevel caving face.
