    Experimental Study on Crushing Characteristics of Lignite under Different Load Conditions by Ziwen Dong

    Published 2022-01-01
    “…Coal particle size and the degree of compaction significantly affect the goaf heritage ventilated environment and the process of spontaneous combustion of coal, the distribution of particle size and compaction degree are also affected by the load size and the application process, and the distribution of stress in goaf is not uniform, resulting in the distribution of particle size and compaction degree of mined-out coal. It is necessary to carry out experimental studies on coal crushing granularity and compaction degree under different loads and loading processes to clarify its distribution law. …”
