Experimental Study on Nonuniform Compaction and Re
·The crushed coal gangue particles are widely used in solid backfilling However the non uniform compaction and internal re crushing behavior of crushed coal gangue under bearing stress have not
Low Temperature Oxidation Characteristics and Apparent
·With increasing mining depth coal is more affected by ground and mining stresses In order to study the characteristics and activation features of coal spontaneous combustion CSC under different stress conditions experiments on low temperature
Fragmentation energy calculation model of coal
·DOI /s11053 024 10444 z Corpus ID 275026951; Low Temperature Oxidation Characteristics and Apparent Activation Energy of Pressurized Crushed Coal Under Stress Loading
Seepage properties of crushed coal particles ScienceDirect
·Coal is a combustible black or brownish black sedimentary rock The crushed rocks such as sandstone mudstone and limestone and so on have been defined as over fractured rocks in previous studies Miao et al 2004 Miao et al 2011 Ma et al 2014 The measurement of seepage properties for crushed over fractured coal cannot be ignored that
Quantitative analysis of layered re crushing of crushed coal
·Quantitative analysis of layered re crushing of crushed coal particles during compression based on CT scanning Author links open overlay panel Guorui Feng a b c Yidie Zhang a b c Zhen Li b c d which is due to the gradual transfer of external load from the top to the bottom After compression the number of particles smaller than 4 mm
The Study of Water Content on the Coal Loading Performance of Thin Coal
·Research has found that the coal loading performance of the ejection loading method is much higher than that of the pushing loading method As the helical angle increases the average loading rate increases the coal working face is a continuous cohesive body before crushing and the crushed coal can be regarded as a discrete loose material
Compressive deformation and energy dissipation of crushed coal
