基于矸石充填技术的急倾斜煤层顶板控制研究

Study on Roof Control of Steeply Inclined Coal Seam Based on Gangue Filling Technology

本文以攀煤集团太平煤矿急倾斜煤层开采为背景,通过分析急倾斜条件下的矸石充填顶板力学模型及矸石充填对顶板控制的影响,设计了矸石充填工艺,并以顶底板变形监测效果进一步说明了矸石充填对急倾斜煤层开采的控制作用。

In this paper,taking Panzhihua group in Taiping Coal Mine of steep coal seam mining as the background,through the analysis of the inclined roof mechanical model and influence of gangue filling on roof control,we design a set of specific process of gangue filling.And the monitoring effect of roof and floor deformation further illustrates the control effect of gangue filling on the mining of steep seam.
