摘要
通过对含夹矸顶煤破碎特点的分析，提出了提高顶煤冒放性的主要技术措施，并在东滩煤矿４３上０２综放面的实践中得到了应用，取得了明显的效果。
After analyzing the characteristics of fragmenting of interbanded roof coal, it is proposed that main measures to improve the caving properties of roof coal. Those measures include : to choose a rational cutting-caving ratio, to use high strength and resistance support, to choose rational mining parameters and advancing speed, to apply a rational caving process, to use necessary auxiliary measures to crush the interband. The measures ever applied at No. 4302 fully-mechanized top-coal caving mining face. The result of the application is significant.
