    Research on Structural Characteristics of Dynamic Nuclear Zone in Dynamic System of Coal and Rock by Hai Rong, Bing Liang, Hongwei Zhang, Feng Zhu

    Published 2019-01-01
    “…Combined with the fracturing technology of liquid CO2, the accuracy of the calculation method for the radius of dynamic nuclear zone is verified in a coal mine in Shanxi Province. The degree of coincidence between the results of the two methods is 96.9%∼97.5%, which shows that the calculation method for the radius of dynamic nuclear zone has high reliability and practicability. …”

    Study on the Compressive Properties and Factors of Recycled Mixture with High Content of Iron Tailings Sand by Yuanshuai Dong, Hong Zhang, Yun Hou, Peng Guo, Jialei Tian, Zhenyu Qian

    Published 2022-01-01
    “…This paper focuses on the disposal of iron tailings sand (ITS) and recycled aggregate of inorganic (RAI) and proposed the “ITS plus RAI” solid waste treatment methods, which uses ITS and RAI as a new base course material to replace new aggregates by 100% to apply in the pavement renovation project of national and provincial roads in Linfen city, Shanxi Province. In this paper, the compressive strength characteristic of recycled mixture with different ratios is studied for the dual waste treatment methods, and the influence factors are analyzed by multiple regression analysis. …”

    Study on Stress Relief of Hard Roof Based on Presplitting and Deep Hole Blasting by Peng Gong, Yongheng Chen, Zhanguo Ma, Shixing Cheng

    Published 2020-01-01
    “…For the problem that the hard roof causes wider end-mining coal pillar, and the roadway is greatly affected by mining, this paper took Shanxi Luning Coal Mine as the engineering background; based on the stress distribution characteristics of the coal pillar, the calculation method of the limit end-mining coal pillar size was given; considering the formation conditions and transmission forms of the advanced abutment stress, a method combining presplitting and deep hole blasting was proposed to weaken the advanced abutment stress. …”
