The realization of scientific production capacity depends on the new technology which is more mechanical, safer and more friendly to the environment. In other words, the thin coal seam can be minable or not refer to that under the current technical and economic conditions, whether the mechanized mining technology can be used and achieve the economic benefits. In order to improve the scientific capacity of the thin coal seam, with the s of mining science, technical economics, system dynamics, analytic hierarchy process and visual basic language, the economical recoverability of the thin coal seam was researched, and the research conclusions are as follows 1. The influence factors and weight of the thin coal seam geological occurrence condition to the drum shearer and plough are determined by the analytic hierarchy process. The geological parameters can be to the VB program to determine the geological recoverability– the adaptability to shearer or plow. Then, whether the thin coal seam can be mechanized mining and which mining technology is better can be judged. 2. The impact of coal mining on the resources and environment is analyzed and quantified, as well as the total cost of thin coal seam mining. According to the dynamic evolution of mining cost, especially the environmental cost, the research on the modeling of the system dynamics is used to get the judgment conditions of the thin coal seam economical recoverability, i.e. the economical recoverability of thin coal seam is based on “output than “. 3. The comprehensive uation index system and the uation criteria of the thin coal seam science productivity are founded. According to the technical and economic parameters of the thin coal seam, the VB program can judge if the scientific production capacity can be realized, and gives the direction to improve the scientific capacity, which is directive to the scientific exploitation of thin coal seam and the realization of scientific productivity. 万方数据 V 4. After the software’s inversion verification with different data, Nantun Coal Mine has operated the software and has got out that the shearer is better to the coal seam, which is directive to the thin coal seam mining. The coal mine’s technology parameters were judged by the software to meet the scientific productivity. 5. In view that the fault has a direct impact on the thin coal seam science capacity, according to the size of the fault, through the UDEC numerical simulation and field practice verification, the solution to improve the scientific productivity has been given as follows （1）Working face rapid passing through fault technology. The fault can be pushed directly if it’s gap is less than 1 m. The fault can be drilled after the presplit blasting if it’s gap is 12m. The fault can be got through by pre dug roadway, if it’s gap is 22.5m. （2）The technology of advancing in the coal thickness change area can be used in geological exploration theory with the bottom to the top cutting based on the preset trajectory, to reduce the working face of rock cutting rate and cut rock volume, and improve the coal cutting machine cutter life-span of coal, an increase of production safety and green degree; （3）Technology of gob side entry to ease the tension, reduce the rock excavation face replacement, the release of coal pillars and other factors to gob successful application in Nantun Coal Mine Based on 2/3 lane is about to save cost and reduce output per meter of about 5 m3, about 8.5m3 mining gangue coal quantity. The economic benefits and environmental benefits increased significantly, greatly enhance the production of machinery and green degree. 6.The innovation points of thispaper are as follows 1Based on the thin coal layer system dynamics principle and of the uation system and model system, puts forward the influence factors of thin coal seam workability of the composition and quantitative s, the research data obtained after verification, the thin seam recoverable and not a scientific judgment and mining technology selection decision the Nantun coal mine; thin coal seam face of uation, the geological conditions of mining and selection process of shearer is better, but in the current coal price situation did not reach the economic recoverable requirements. 2The construction of thin coal science capacity comprehensive uation index system and uation standard, in the thin coal seam can achieve scientific 万方数据 VI judgment on the basis of the production, and gives its suggestions for improving the direction of scientific productivity; uation system for empirical application in thin coal seam mining in Nantun coal mine, the mine has produced 3602 in thin coal seam face at that time under the conditions of the scientific production scale of 78, to achieve the scientific productivity, 3605 thin coal seam to be mined at this stage can not achieve scientific productivity. 3Three connotations of scientific productivity mechanical degree, production safety, production based on green degree, put forward to improve the scientific capacity of thin coal seam technology roadmap, based on fast fault theory, “with the bottom to the top“ coal thickness fluctuation region and gob technology should be mainly used in thin coal seam the key to improve the scientific production technology system, and were successfully used in thin coal seam five 222120 3601 thin coal seam of Huaibei Mining Group 7122 thin coal seam in Qinan Coal Mine, Pingdingshan Coal Group Pingyu coal mine and Yanzhou Mining Group in Nantun coal mine, improve the scientific capacity of thin coal seam working face This paper has 55 figure, 52table and 186 references.
