冻结矿物料的物理力学性能及清理方法

Physical and Mechanical Properties of Frozen Mineral and Its Clearing Method

提出冻结矿物料是一个复杂的多相体系,阐述了各单相体系之间的相互联系与作用、外界因素对冻结矿物料的物理与力学性能的影响。为寻求最佳解决冻车结底的清理方法提供理论依据。

It has always been a technical difficulty that the mineral material tends to freeze firmly at the bottom of mining car in cold winter. Great attention has been paid to this problem both within China and abroad. In this paper,the frozen mineral material is suggested to be considered as a complicated heterogeneous system,The relations and interactions between each homogeneous system and the physical and mechanical properties of the frozen mineral material influenced by outside factors are discussed in order to reveal theoretical findings for the best clearing method to solve troubles of frozen bottom of mining car.
