通过对“三软”不稳定煤层条件下不同放煤方法的对比，提出了单轮顺序连续两口或多口的放煤方法。经试验表明，单轮顺序放煤工艺具有放煤速度快、回收率高、含矸率低和灰分低，工人易掌握等优点，是适应“三软”不稳定厚煤层开采的一种有效方法。 By comparing the different caving methods under the condition of “three soft” unstable coal seam, a coal caving method with two or more consecutive single wheels is proposed. The tests show that the unloading sequence of single round coal has the advantages of quick release rate, high recovery rate, low refuse content, low ash content and easy mastery of workers, which is an effective method to adapt to the “three soft” unstable thick seam mining .
