随着我国煤矿开采强度的不断加大，特别是前些年不加节制的“掠夺式”开采，使赋存条件良好的煤层储量越来越少，赋存条件较为复杂煤层的开采越来越多，大倾角煤层开采的问题日益突出。大倾角煤层倾角大，侧向力大，工作面支架、输送机和采煤机的稳定性差，易于倾倒下滑。为此，提出工作面“三机”防滑措施，经过在盐井一矿首采工作面现场试验，获得了较好的防滑效果，适合推广应用。
隨著我國煤礦開採彊度的不斷加大，特彆是前些年不加節製的“掠奪式”開採，使賦存條件良好的煤層儲量越來越少，賦存條件較為複雜煤層的開採越來越多，大傾角煤層開採的問題日益突齣。大傾角煤層傾角大，側嚮力大，工作麵支架、輸送機和採煤機的穩定性差，易于傾倒下滑。為此，提齣工作麵“三機”防滑措施，經過在鹽井一礦首採工作麵現場試驗，穫得瞭較好的防滑效果，適閤推廣應用。

With the increasing of the coal mining strength continuously in our country,especially the with out restraint "predatory"mode of production a few years ago,which makes the coal reserves with good occurrence conditions lesser and lesser,more and more coal seams with complex occurrence condi-tions are mined,so,the mining problem of greater tilt angle increasingly prominent.The dip angle of the coal seam is large,and its lateral fore is big,besides that,stability of the face support,conveyor and coal winning machine are poor,and easy to dump.Thus,the slippery measures of "three machines"are proposed,the field test results of the mechanized mining face of Yanjing No.1 coal mine show that,good anti-slipping effects is obtained,and the above measures,is suitable for promotion.
