煤炭开掘工作面岩溶陷落柱合理开采技术

煤炭资源是全球稀缺的自然资源之一,对人类的生存发挥着至关重要的作用,而对于煤层气资源的利用,国内外专家也在通过不懈的努力,力求达到更好的开采效果,但在实际开采中仍然遇到很多难题,其中最为典型的就是"陷落柱"问题。就煤炭开掘工作面岩溶陷落柱的合理开采技术做出了探讨,对岩溶陷落柱的特性进行了说明,同时表明岩溶陷落柱对煤矿开采所造成的影响,介绍了采用大功率采煤机时,煤矿开采所使用的机械切割技术与松动爆破技术,并且采用现代化的顶板管理方法,如超前支护等实现对煤矿开采的综合治理,在生产实践中获得非常理想的效果。

Directions of changes of hard coal output technologies in Poland

The author presents the results being the effect of the analysis of innovative rate of individual technologies applied in opening up,development and extraction works which was carried out within the project:"scenarios of technological development of hard coal extractive industry".After presentation of opening up,development and extraction technologies that are applied in Polish hard coal industry and their classification with regard to innovation degree the author describes those technologies in a detailed manner.He brings attention to the most effective systems for hard coal deposits’ opening up,development and their extraction,including the extraction of the residual coal.The attention is also paid to the safety level of the applied technologies.
