摘 要:根据顶煤的放出规律,研究了放煤参数与煤层赋存条件之间的关系,通过分析认为可以依据煤层厚度和煤层松散系数来确定合理的采放比、放煤间距、放煤步距等开采工艺参数,从而解决了采放工艺参数靠经验类比,缺乏科学依据的问题。According to top coal drawing law of roof coal caving, the relation between coal drawing parameters and coal seam occurrence conditions were studied. Through analysis it considered that coal seam thickness and coal seam loosening coefficient could be used to determine rational mining and caving ratio, coal drawing spacing and coal drawing pace so that it solved the problem to determine the mining and caving process parameters by experience.
