摘要: 为了充分利用侏罗系煤高热量低硫低灰分的优势,保护侏罗系煤炭资源,延长矿井的服务年限。因此,提出了对石炭二叠系煤层的开采利用研究,通过石炭系与侏罗系煤炭配煤入选,以实现煤炭利用率效益最大化。通过对石炭二叠系的研究发现,结果表明石炭二叠系煤层储量丰富,但热值与侏罗系相比较小。通过对石炭二叠系煤层经济效益,开采条件,煤质等方面的研究,论述了石炭二叠系开采的价值,得出了石炭系延伸的可行性。

Abstract: In order to make full use of the advantage of low-sulfur Jurassic coal ash, to protect the Jurassic coal resources, to extend the service life of the mine. Therefore, a study of the exploitation of the Permo-Carboniferous coal seams, Carboniferous and Jurassic coal blending selected to maximize the benefits of coal utilization. Discovered through the study of the Permo-Carboniferous, the results show that the Permo-Carboniferous coal is abundant, but the calorific value is pared with the Jurassic. Tentative Permian coal seams: economic benefits, mining conditions, coal, discusses the Permo-Carboniferous mining the value derived Carboniferous feasibility of extending.
Key words: The Jurassic coal; Permo-Carboniferous coal; mining conditions; utilization value
引言
通过查阅《煤矿安全规程》《煤炭工程》《煤炭科技》《同煤科技》《煤炭学报》等资料,了解开采石炭系的可行性和实效性。《煤炭学报》曾阐述:随着浅部煤炭资源的逐年减少甚至枯竭,地下开采的深度越来越大,越来越多的矿井将面临从侏罗系煤向石炭系延伸的处境和必然之路。《同煤科技》指出:随着侏罗纪煤层储量的逐渐减少,其中厚煤层所占比例越来越小,而下部石炭系厚及特厚煤层赋存丰富,开采能力将越来越
