底板巷穿层钻孔在煤巷掘进中的应用

Application of Crossing Hole of Floor Roadway in Coal Roadway Drivage

随着国内煤矿开采技术的不断提高,如何提高开采量及提高开采的效率问题摆在我们面前,随着国家提出了"可保尽保,应抽尽抽"的战略方针,在这个战略方针的指导下,国内各大型煤矿对原煤的开采技术进行了技术挖潜和技术革新,研制成了底板巷穿层钻孔技术,该项技术对煤巷掘进过程中,煤瓦斯突抽放的效果显著,确保矿井的稳产、高产及安全生产。

With the continuous improvement of coal mining technology in China, people have to face the problem that how to improve the production and efficiency of mining. The strategic concept of"Protecting the mine which should be protected, extracting the mine which should be extracted" is put forward. With the guidance of this strategic concept, technology development and technology innovation are carried out for the mining technology of raw coal by the various of large coal mines in China. The technology of crossing hole of floor roadway is developed. This technology has good effect on the coal gas drainage in the process of coal roadway drivage, and it ensure the stable yield high yield and safety production of the mine.
