第四次国家自然科学奖评选最近在北京揭晓。中国矿大钱鸣高、李鸿昌、朱德仁、赵国景研究的《采场上覆岩层活动规律》荣获三等奖。《采场上覆岩层活动规律》系统地研究了采场矿山压力及其控制问题,发现了已破断的岩块互相挤压后形成“砌体梁”平衡结构,根据老顶所处的各种边界条件,获得了老顶作为“板”形式的各种破断方式及规律,提出了弹性板和梁的力学模型。这一研究成果达到国际先进水平。
The Fourth National Natural Science Award was recently announced in Beijing. China Mining big money Minggao, Li Hongchang, Zhu Deren, Zhao Guojing research “stope overlying strata movement rule” won the third prize. The law of overlying strata in stopes systematically studied the mine pressure and its control problems in stope and found that the crushed rock blocks formed a balanced structure of “masonry beams” Boundary conditions, get the old roof as a “plate” forms of various breaking methods and laws, put forward the elastic plate and beam mechanical model. The research results reached the international advanced level.
