Abstract: In this article, it took the high rank coal reservoir coalbed methane in Panzhuang block of Jincheng mining area as the research object. Through collecting, arranging and studying the basic geological data, development model and coalbed methane drainage data, it analyzed the influence factors of coalbed methane recovery, and used the isothermal adsorption curves and numerical simulation method to predict the coalbed methane production and recovery rate in the research area. Finally, it used numerical simulation to optimize the drainage process of coalbed methane in this area. The results showed that two methods were adopted to predict that the recovery rate of this research area was in the range of 49.24% to 51.8%. Through the drainage process optimization, it obtained that the optimum well spacing was 300 m.
