Life and career

Li was born into a rural family; he once served as a commune cadre in 1975. In 1978, he entered the Mining Engineering Department,

Research

Li began to develop Water Jet TBM Tunneling Machine when trained at UC Berkeley. There, he spent two years to make the machine capable of crushing stones which are extremely hard. He continued this research after he returned to Chongqing University. He finally developed a method of rock crushing, containing eroding coal rock with water jet, crack extension, washing away the debris, and cooling the cutting-tools. Li and his colleagues studied the mechanism of abrasive mixing in

flow, and measured its effects on main parameters, so they could develop the equations about jet parameters and cutting effection. Consequently, they could infer the relation between characteristics of wear particles and effect of cavitation in pulsed abrasive water jet. Based on this, they proposed a design standard of pulsed abrasive water jet nozzles.袁成琛主编. 教育部“跨世纪优秀人才计划”成果选编第2辑上. 北京市：高等教育出版社, 2004.02. 页39.
