摘要
介绍了一种全新的破煤方式——冲击式破煤及其工程背景，分析了回采工作面煤壁的物理及力学特性，进而提出了冲击式破煤的物理模型，并对冲击破煤机理进行了初步的探讨。
A new cutting method——impact cutting and its engineering background was introduced.After analyzed the physics and mechanics characters of the coal wall of the working face,a physical model of impact cutting was posed,and its theory was studied initially.
