以陶一矿超高水材料开放式充填开采为背景,介绍了超高水材料开放式充填开采效果的评价方法,并对其覆岩控制效果进行了分析和评价.结果表明:超高水材料的渗透效果与存在裂隙的多少及其导通性有关.采用该方法进行充填开采后,充填率可接近90%,覆岩控制效果良好,地表未发生明显变化,采空区及其顶底板岩层中几乎所有导通的缝隙和部分离层空间都被超高水材料充填密实,工作面瓦斯含量也有明显降低.
Based on the open-fill mining of ultrahigh water material in Tao-Yi Mine, the evaluation method of open-fill mining effect of ultrahigh water material is introduced and the control effect of overburden rock is analyzed and evaluated.The results show that ultra-high water material Of infiltration effect is related to the existence of cracks and its continuity.With the method of filling and mining, filling rate can be close to 90%, overburden control effect is good, the surface did not change significantly, the goaf and its top and bottom rock Almost all of the conduction gap and part of the separation space are ultra-high water material filling density, gas content of the face has also been significantly reduced.
