The mining techniques and current situation of equipment in developed countries and China in thin coal seam are compared. Ac-cording to the complex structure and extra length of No. 2203 face in Shayu coal mine, the efficient mining techniques under condition of complex structure are formed by innovating and improving the structure of the coal shearer, scraper conveyor, and hydraulic support. The techniques were applied in actual production and good economic effect was achieved.
