    山东巨野矿区深部土工程地质性质及建井意义

    STUDY ON THE ENGINEERING GEOLOGICAL PROPERTIES OF THE DEEP SOILS IN JUYE MINE AREA OF SHANDONG PROVINCE AND IT'S SIGNIFICANCE TO THE SHAFT BUILDING

    • 摘要: 介绍了即将建设的特大型能源基地山东巨野矿区的基本情况。概述了矿区巨厚土层的地层结构及其基本组成特点。以龙固矿井筒检查孔为例,测试分析了深部土基本工程地质性质,对粘性土的粘土矿物成分进行了相对定量分析,对其膨胀性进行了分类;对砂土的粒度组成和渗透系数进行了测定。模拟深部地层应力大小及井筒开挖卸载特点,进行了深部粘土样三轴高压卸载试验,得到了相应的变形曲线和强度参数。分析了巨野矿区立井穿过厚表土层将要遇到的主要工程地质问题。研究对巨野矿区立井建设设计和施工有重要的应用价值。

       

      Abstract: The basic information of the large type energy base of Juye mine area in Shandong province is presented. The geological strata and it's basic constitute characteristics are also introduced. Taking Longgu mine shaft as an example, the basic engineering geological properties of the deep soils are tested and analyzed, the clay mineral composition of the deep clay soils are tested quantitatively, the swelling properties are also tested and classified. The grain constitute and permeability of the sands are also tested. Imitating the characteristics of the deep strata stress state and unloading during the shaft excavation, the high pressure triaxial unloading testing are finished with the deep clay sample, which obtained the corresponding stress-strain curves and the strength parameters. The main engineering geological which probably arise during the shaft building through the thick over soils are analyzed. The researches have an important value for application to the design and construction of the shafts of Juye mine area.
