摘要:
本文对平朔矿区综放开采的顶煤放出规律进行了研究,针对平朔4#煤、9#煤进行了顶煤放出的相似性模拟试验,得出了不同采放比、使用不同开采方式下顶煤放出含矸率及顶煤放出率的相对关系。通过实验数据分析,得出了平朔矿区综放开采的合理放煤工艺为一采一放。在现场实际放煤过程中,可将煤流中的矸石比例达到1/5作为终止放煤的依据。
关键词: 综放开采, 采放比, 含矸率, 放煤工艺
Abstract:
Studied the top-coal movement and running of full-mechanized caving mining in which Pingshuo mining area,the simulation experiment on the rule of top-coal movement and running was done for the Pingshuo 4# , 9# coal ,obtained the relation of coal-gangue content and top coal drawing ratio in the different of mining and caving ratio,and the different exploitation method.The experimental data show that the reasonable exploitation method at Pingshuo mining area is one cut by one drawing. In the process of coal caving ,it can take 1/5 of gangue ratio among coal-gangue flow on drawing jaws as the criterion of ending drawing top coal.
Key words: full-mechanized caving mining, mining and caving ratio, refuse content, top coal caving technology
