Changhsingian Radiolarian Fauna from the Meishan D Section and Sea-Level Changes;

Organic and inorganic carbon-isotope shift and paleoenvironment at the P-T boundary section in Meishan,Zhejiang Province;

The Permian-Triassic boundary GSSP at Meishan,Changxing,is designated within bed 27.

Analysis of the roof-fall and collapse accident in non-coal mine;

Research and development of statistical management system for casualty accident in non-coal mines;

Discussion on reasons of personal casualty in non-coal mine and the countermeasures;

Stabilities in underground mined-out areas of non-coal mines in China;

The number of non-coal mines in China amounts to more than 110,000,employees more than 1,000,000,the people suffer from occupational diseases around 800,000,and the number is increasing more than 30,000 each year.

Water dynamics of the 280 coal gangue dumps in Yangquan City, Shanxi Province was preliminarily studied by the analyses of physical properties, water infiltration characteristics, and water content of the weathered gangue.

In this paper, borrowing ideas from the research method of the spontaneous combustion mathematical model of goaf, applying to the hydrodynamic theory of porous medium, the spontaneous combustion mathematical model of coal gangue dump is set up.

Study on the wind velocity of coal gangue pile in growing season in Fuxin mining area,Liaoning Province;

The authors take Sunjiawan coal gangue pile of Fuxin mine area as the research object,using the principal component analysis to fix on the weight of the indexes and summing the grades of each evaluation unit to calculate the comprehensive index,to evaluate vegetation restoration suitability in each site unit with different dumping years.

Vegetation restoration is one of available approach for coal gangue pile fathering,the special soil condition of coal gangue pile such as high temperature,acidification, salinity etc.
