大阳煤矿3204工作面位于二采区背斜南翼，煤层倾角平均为15°，最大为25°，是典型的大倾角双斜工作面。在回采过程中通过保证采煤机及液压支架的稳定性防止了其倾倒、侧翻事故的发生。同时通过加强工作面煤壁、顶板管理，保证支架、单体支柱初撑力，以及对破碎煤体注射玛丽散提高了煤体的整体性，减少了煤壁片帮、冒顶事故的发生。通过工作面调斜减小了支架发生倾倒及刮板输送机向进风顺槽打滑下串的可能。最后在回撤设备时因地制宜的利用了底板的自然坡度，以及通过撤架通道支架的护帮板来平衡被拖移支架的侧向下滑力，确保了支架的顺利回撤。通过对3204大倾角双斜工作面的成功回采，不仅为本矿类似工作面的开采打下了很多好的基础，同时也为其他矿井双斜工作面的安全开采提供了借鉴。

The 3204 working Face of Dayang coal Mine is located in the section mining area of south limb which is a typical dual-slope in-clined face with average seam angle 15 °, maximum of it is 25 °.In the recovery process by ensuring the stability of shearers and hydraulic support prevent it from tipping over and rollover accidents take place. By strengthening the management of coal wall and roof management, guarantee bracket, single Prop' initial support force, as well as injection Malishan on the broken coal to improve the integrity of coal,so as re-duce the coal wall spalling and roof fall accident take place. By adjusting oblique face reducing the change that bracket could dumpe and scraper conveyor slip to the wind string, ensure the smooth retracement. By the successful recovery of 3204 high double oblique elevation, Not only make a good foundation for the similar working face but also provide a reference for the other mine ' s safety mining of double oblique face.
