Establishing coal pillar width and the mining width were two of the most important factors in the process of strip mining， not only related to the recovery rate of coal resources， but also made a difference in stability of coal pillar， rock destruction and surface subsidence. In order to determine optimum width of coal pillar and mining width in mining process of 1109 working face， design and optimization of mining plan were analyzed. Optimum mining width of 1109 working face was 58.8m， and optimum design of coal pillar width was 39m according to its theoretical calculation. The stability of coal pillar was analyzed by numerical simulation method， and the results showed that the size of coal pillar was scientific and reasonable.
