我国进行矿产资源的开发主要通过煤矿开采这一形式,煤矿开采技术在先进时代各个行业生产技术均不断创新与发展的背景下亦获得了较大程度的改进,全新开发方法与技术的应用使得我国在煤炭开采效率和安全上更加有保障,更能够满足我国在煤炭资源方面的需求。本文主要对煤炭开采中矿井预注水软化坚硬顶煤这一技术进行分析和研究,在了解预注水软化顶煤的机理后明确了应用预注水软化顶煤技术的必要性。在此基础上,本文进行了厚煤层矿井预注水工艺参数的设计,并且探索了中硬煤层预注水工艺参数的设计与应用。
China’s mineral resources development mainly through the form of coal mining, coal mining technology in the advanced era of various industries are continuous innovation and development of the background has also been a greater degree of improvement, the application of new development methods and technologies make our country More secure in the efficiency and safety of coal mining, and more able to meet the needs of China’s coal resources. This paper mainly analyzes and researches on the technology of coal top pre-water softening of hard top coal. After understanding the mechanism of pre-injection softening top coal, it is necessary to clarify the application of pre-injection softening top coal technology. On this basis, this paper carries out the design of pre-injection process parameters of thick coal seam mine, and explores the design and application of pre-injection process parameters of medium-hard coal seam.
