摘要
煤炭作为我国重要的能源形式,进行煤炭综采过程中,提高放煤技术能够提高煤炭的产量及质量.放煤步距作为放煤过程中重要的工艺参数,必须针对不同的煤层选择合理的放煤步距.采用实验分析的形式对厚煤层的放煤步距进行模拟实验,采用不同颜色的石子模拟顶煤及直接顶的流动作用,经过实验对一采一放、两采一放及三采一放三种不同的放煤步距产生的顶煤进行分析,从而对煤矿的开采提供应用参考.
Abstract
Coal,as an important form of energy in China,can improve the production and quality of coal through the improvement of coal mining technology in the process of comprehensive coal mining.As an important process parameter in the coal mining process,the coal mining step spacing must be selected reasonably for different coal seams.Using experimental analysis,a simulation experiment was conducted on the coal release step spacing of thick coal seams.Different colored stones were used to simulate the flow effects of top coal and direct top coal.Through experiments,the top coal produced by three different coal release step spacings,namely one mining and one release,two mining and one release,and three mining and one release,was analyzed to provide application references for coal mining.
