特厚煤层开采方法与设备选型研究

Study on Mining Method and Equipment Selection of Extra Thick Coal Seam

针对特厚煤层开采方法选取和设备选型的难题,比较了三种开采方法的优缺点,最终选择了放顶煤开采方法;针对工作面的实际情况,利用理论计算和三机的原则,对工作面开采设备进行合理选型,并在实际生产中取得了良好效果,为今后类似工作面的设备选型提供了借鉴意义。

As to the problem of the selection of mining method and equipment selection for extra thick coal seam,the advantages and disadvantages of the three mining methods are compared.Finally,the method of top coal caving is selected.Take the working face as the engineering background,using the theoretical calculation and the principle of mating,the working face mining equipment is rationally selected,which achieves good effect in actual production,providing reference for equipment selection of similar working face.
