深部矿井大采高大比例相似模拟实验复杂性探析

随着深部矿井综采技术的发展,对近水平厚煤层走向长壁综采工作面的研究已势在必行,然而深部矿井大采高、大比例相似模拟实验却异常复杂难做,存在垮落步距大、冒落高度大、垮落体易破坏、工作面支架移架困难以及埋深难以模拟等一系列复杂性,对其复杂性进行探析具有一定的意义。

The Complex Analysis of Similar Material Simulation for Large Mining Height and Large Proportion about Deep Mine

With the development of fully mechanized mining technology in deep mine,the research of fully mechanized longwall face in nearly level thick coal seam is imperative under the situation.However,similar material simulation by large mining height and large ratio about deep mines is very complex and difficult,and there is a series of complexity: such as long fall step,large cave height,falling rock body that is destroyed easily,the difficulty to move brace,and trouble simulation according to the bury depth etc.So the research of the complexity is actual signification.
