矿山开采中涌水突水涌沙淹井实验研究都需进行固液耦合相似材料实验,但长期来由于没有寻找到合适的相似材料,井工采矿固液耦合实验一直没有突破性的进展.通过大量试验筛选,得到石蜡适合作固液耦合实验的胶凝剂,并作出试件物理力学参数随不同相似材料配比的变化规律,从而获得榆神府矿区各岩层相似实验配比.针对榆神府矿区沙基型覆岩及富水特点,进行了固液耦合水资源保护实验,采用间歇式开采.得出了从不同基岩厚度工作面实现保水开采的合理推进距.图4,表2,参10.
However, in the long run, no suitable material has been found, so there has been no breakthrough in solid-liquid coupling experiments of well drilling and mining. The results show that the paraffin can be used as the gelling agent in the experiment of solid-liquid coupling, and the changing rules of physical and mechanical parameters of the specimen with different similar materials are obtained, and the similar experimental ratios of the strata in Yushenfu mining area are obtained. Mining area sand overburden and water-rich characteristics of the solid-liquid coupling water resources protection experiments, the use of intermittent mining obtained from the bedrock thickness of the face to achieve water-saving mining reasonable push distance.Figure 4, Table 2, Participation 10.
