薄基岩浅埋煤层过沟安全开采技术

Crossing Ditch Safety Mining Technology of Shallow Seam Covered with Thin Bedrock

摘要: 以哈拉沟煤矿22404-2工作面过沟开采为背景,提出了薄基岩浅埋煤层过沟安全开采技术。首先对过沟开采期间可能发生的事故进行预测,然后采取相应的预防事故发生的技术措施,最后对技术措施应用效果进行分析。生产实践结果表明,薄基岩浅埋煤层过沟安全开采技术的应用是成功而有效的,为神东矿区类似条件下开采提供参考和借鉴。

Abstract: Safety crossing ditch mining technology of shallow coal seam covered with thin bedrock is put forward by taking 22404-2 working face of Halagou coal mine crossing ditch as background.First of all,forecast the accidents that may occur during crossing ditch mining,and then take the appropriate technical measures to prevent accidents.Finally,analyze the application effect of technical measures.Production practice results show that the technology is successful and effective,which provides reference for mining in Shendong area with similar mining conditions.
