    Experimental investigation of the precursor characteristics and early warning of coal burst based on quantitative analysis of acoustic emission signals by Xiaoling Zhao, Zhiyi Liao, Xiufeng Zhang, Cong Shen, Jianbo Zhu

    Published 2025-01-01
    “…Abstract Coal burst is one of the most frequent and destructive dynamic disasters encountered during underground mining engineering. However, the understanding of quantitative precursor characteristics of coal burst is still in its infancy, rendering it difficult to provide effective early warning of disaster. …”

    Study on the safety distance determination model for natural gas wells in Ordos Basin subsidence areas of coal mining by Wen Wang, Yang Zhang, Shuang Gong, Junqi Lei, Jiandong Ren, Yanxiong Ding, Xiaowei Lu

    Published 2025-01-01
    “…Abstract To optimize the safe distance between coal mining faces and natural gas wells, with the Ordos Basin as the engineering background for the intersectional development of natural gas and coal resources, a Gaussian function equation for subsidence curves under complete mining was proposed based on the probability integral method, and a model was constructed to determine the coordinated mining safety distance between coal mining faces and natural gas wells. …”
