This paper, by making an anlysis of the Coal-bed methane existed condition in Zhangji Mine of Huainan Coal Mine Administration and the influence of the curtaingrouting on the discharging of methane, has studied and worked out the safe coal-openning measures by sinking the vertical well,which has received a good safe coal-opnning result.

When advancing and uncovering coal in roadway, better construction method is vibration shot, metal framework, borehole bleed-off and hydraulic hole, of which vibration shot is principal.

Using all coal digging methods as a reference,synthetical cutting through coal seam measure is designed.

In this article,the situation of cutting through coal seam in the main and auxiliary mine shaft is introduced,then the main factors of natural distressed zone formation are proposed,finally, the main reasons for cutting through coal seam outburst in the auxiliary mine shaft are also analyzed.

According to the shortage of the conventional seam opening methods and in combined with the actual problems of the seam opening outburst in Panbei Mine,base on the detail analysis on the outburst control measures at home and abroad and with the optimized borehole design,an rational outburst control result was obtained.

Research about coal mine security management based on spatial data mining;

This article analyzed the reasons for the frequency coal mine security accidents from objective and subjective separately in view of coal mine security situation in China,and proposed the countermeasures.

In this paper, consistency between the model of coal mine security and the model of fuzzy control is analyzed under the consistence of data input and data output.

Design of lightweight type silt coal loader for water sump based on mine safety;

Discussion on several issues of mine safety monitoring and control system;

Application of Grey Markov Mode to predict mine safety accident;
