摘要:

隨著我國社會經(jīng)濟(jì)的快速發(fā)展以及人們生活水平的不斷提高,我國的能源需求量也變得越來越大。所以依靠先進(jìn)的科學(xué)技術(shù)促進(jìn)煤炭生產(chǎn)力的提高、礦井高效生產(chǎn)的實現(xiàn)變得越來越重要。本文針對厚煤層大采高綜放開采的煤巖冒放規(guī)律及放煤工藝參數(shù)研究進(jìn)行了分析和研究,供大家參考。

Abstract:

With the rapid development of our social economy and the unceasing enhancement of people's life level, China's energy demand is also becoming higher. So relying on advanced science and technology to improve coal productivity and achieve the realization of the efficient production is becoming more and more important. This article studied the coal rock caving laws and technological parameters of top-coal caving of fully mechanized mining with great cutting height for thick coal seam, for your reference.
