煤矿回采工作面技术创新及应用
|
摘要
在煤矿生产作业过程中,回采工作面在其中起着举足轻重的作用,它是煤矿企业直接生产煤炭开采煤层的重要场所。在一些地质较为复杂多变的情况下,回采工作面安全生产效益长久以来困扰众多煤炭企业,也一直是企业和科研单位的技术难题。本文从回采生产过程中的落煤、出煤、矿压等多方面入手,探讨了技术创新在回采工作面的实践和应用。
In the process of coal mine production and operation, mining face plays a vital role in it. The mining face is an important place for coal mining enterprises to produce coal directly. In some complex and changeable geological conditions, the safety production efficiency of mining face has long been a problem for many coal enterprises, and it has been a technical problem for enterprises and scientific research units. In this paper, the practice and application of technological innovation in mining face are discussed from the aspects of coal falling, coal drawing and rock pressure in the process of mining production.
