煤体的强度一般小于岩体，煤巷在掘进过程中与岩巷围岩的力学特征不同，尤其是煤巷快速掘进时。为获得煤巷快速掘进时巷道围岩的力学特征，采用数值模拟的方法，建立了三维计算模型，研究了煤巷掘进过程中围岩的力学特征，研究成果将为煤巷的支护提供一定依据。
煤體的彊度一般小于巖體，煤巷在掘進過程中與巖巷圍巖的力學特徵不同，尤其是煤巷快速掘進時。為穫得煤巷快速掘進時巷道圍巖的力學特徵，採用數值模擬的方法，建立瞭三維計算模型，研究瞭煤巷掘進過程中圍巖的力學特徵，研究成果將為煤巷的支護提供一定依據。

The strength of coal body was lower than that of rock, the mechanical characteristics of coal roadway and rock roadway was different in the process of rapid excavation, especially when coal roadway fast driving. To obtain mechanical characteristics of sur-rounding rock when rapid excavation, the paper established a three-dimensional computational model to study the mechanical character-istics of the process of coal roadway driving rock, the result will provide some basis for the support of coal roadway.
