针对传统镐齿破碎岩石的损耗严重，提出一种冲击滚压破碎方式。其结构采用冲击机构和滚压机构配合破碎岩石，考虑影响硬岩掘进机刀具的寿命、可靠性、掘进效率因素，采用多学科优化方法构建硬岩掘进机破碎机构布置关系，并以全局协调优化为主导，总体协调优化参数，对破碎机构的布置进行冲击参数、刀具受力、切削参数、围岩属性的匹配研究。研究结果表明：该硬岩掘进机破碎机构布置方法可行，降低了硬岩掘进机能量消耗、刀具的磨损，提高了掘进效率，使整机性能达到最优。

Hard rock roadheader is the key equipment in laneway constructions. In view of the traditional point-attack picks sever loss while breaking rocks, this paper put forward a shock and rolling breaking method which utilizes impact mechanism and a rolling mechanism to break rocks. This study analyzed the duration, the reliability and the driving efficiency on the cutter of the hard rock tunnel boring machine, and optimized the relations between the hard rock crushers using multi-disciplinary optimization method. In addition, this paper researched on factors that influence the layout of crushers which include global coordinating optimization as main factor, coordinating the optimization of parameters, the impact parameter, cutting force, cutting parameters and rock properties matching. The results of study show that the arrangement of the hard rock crusher was feasible, and it is optimal in energy consumption, tool wearing, driving efficiency and overall performance.
