摘要
薄煤层开采在煤矿开采中具有重要意义,可以作为下层煤的矿压解放层,也可以作为下层煤的瓦斯保护层。老石旦煤矿12#煤层厚为1.10~1.20m,且煤层断层构造较多。1209综采工作面切眼出现两个正断层,对工作面正常回采产生影响,老石旦煤矿采用薄煤层综采工艺后,总结出一些复杂地质条件下薄煤层综采的方法,并取得良好效果。
Thin seam mining has a great significance, it is not only as the below layer liberated seam, but also as the gas cover .1209 fullymechanized face cuthole appears two normal faults, which has a great influence on the normal stoping. After adopting the thin seam mining, summarize some thin seam mining method in complicated geological conditions and have a great effort.
