Mine workplace risk prevention management Mining workplaces are evaluated by using LEC, evaluation results indicate that the place is highly dangerous and requires immediate rectification.Considering that enhance security management can reduce system reality in real danger, risk analysis methods are appropriate for the job conditions.Namely increases a parameter in the original mathematical model foundation M,Called safety management factor,Mainly related to four aspects of security management：M：Job personnel management, M:Equipment management, M：Materials management, M： Working environment management.Therefore, security management coefficient can be expressed as: .By strengthening safety management, improved LEC law can be expressed as a formula: Four management coefficient of the safety control coefficient sees the Table 6~Table 9.
Managing content Range of values 1 Protective products management 0.95—1 2 Protection thing periodic maintenance management 0.95—1 3 Mechanized, automatic equipment management 0.95—1 4 Airtight remote control device management 0.95—1 Table8 Coefficient of materials management No.
(3) LEC method combined with a Markov model, is important to the mine pneumoconiosis science forecast, the effective prevention, the control pneumoconiosis disease incidence rate, simultaneously provides the scientific basis for the sanitary supervision management.

Tribological Study of Xanthate-containing Acetic Ester as Additives in Hydrogenated Oil Li Chaolong 1, Xiong Liping1,Liu Hong1, Xiong Liting2, Wang Wei1 1School of Basic Science, Eastchina Jiaotong University, Nanchang 330013, PR China 2School of computer science and software engineering, Nanchang Institute of Technology, Nanchang 330013, PR China Keywords: Acetic ester derivative; additive; hydrogenated oil; tribological mechanism Abstract.A novel ester derivative, dodecyl xanthate acetic dodecyl xanthate ester(DXAD) was synthesized and it’s tribological behaviors as additives in hydrogenated oil, were evaluated using a four-ball tester.
In the paper, we use xanthate as raw material, to synthesis a kind of xanthate-containing ester derivative, which accord with biodegradable request of lubricating oil additive.
