| Abstract: | Taking the briquette made by outburst raw coal as the sample,we tested the mechanical properties of gas-containing coal in the process of loading and unloading and studied the effect of gas on mechanical properties of gas containing coal.The results show that the residual deformation produced in loading and unloading process of outburst is very great and the deformation modulus in the loading process is smaller than that in the unloading process.The shape of curve formed in the loading process and unloading... |
