this article gave an initial probe into fill system, stope standard, slice height, landing method, stopping structure, paving material & stope supporting according to the flat-backcut-and-dry-placed-fill technology

The structure, paving techniques and the future of some type of polyurethane plastic playgrounds, such as the coiled plastic course with surface embossing, the plastic course with granular surface which sprayed by mixture of rubber pellet and polyurethane prepolymer, low cost two layer plastic course, and special paving material were introduced.

In order to eliminate the shortcoming of sintering without bed, the study on use of limonite as sintering bedding material was performed The better sintering indices can be obtained with use of Wutonggou limonite as sintering bedding material, crystalline water can be completely removed and carbonate can be completely dissociated by calorific heat produced during sinterin

The laboratory test of Hainan iron ore as bedding material was conducted in the sinter pot.

By the improvement of grinding process of the component A of two component polyurethane paving materials, the production cycle is shortened, and the energy consume is reduced.

A low cost polyurethane paving materials were produced by studying compositions and ratio of polyurethane elastomer admixture.

Study of control system of paving stock mechanism of new-type machining tool about rapid prototyping manufacture for ceramic parts;

A machine tool about rapid prototyping manufacturing for ceramic parts which is based on the technology of laminated coalition and rapid concreting prototyping for ceramic parts has been designed, and the basic constitutions of the paving stock mechanism of it have been introduced.
