田陈煤矿7112综放工作面首次揭露陷落柱,由于陷落柱具有导水性特点,防治水是安全生产的重点,通过查资料和现场使用瞬变电磁仪进行探测,确定其赋存情况,提出过陷落柱方案,经过对比科学论证,确定可行性方案,经过改变劳动组织,优化劳动方式,采取两班打眼放炮,两班组织生产,加快推进速度,采用钻爆法崩落岩石,煤机滚筒装岩强推硬过方式过陷落柱。期间采取了许多新措施,积累了许多好的经验和方法,而且为以后遇到类似情况提供了宝贵经验和技术支持。
As for the first time, the collapse column was exposed in 7112 fully mechanized caving mining face of Tiantan Coal Mine. Due to the characteristics of water conduction in the sinking column and prevention and control of water, it is the key point of safety production. Through investigating the data and using transient electromagnetic instrument to detect on site, Collapse column program, after comparing the scientific feasibility studies, to determine the feasibility of the program, after changing the labor organization, optimizing the mode of labor, to take two classes shot blasting, two organizations to organize and accelerate the pace of drilling and blasting with rock and coal mining drum rock Push the hard way over the collapse of the column. During this period many new measures have been taken, many good experiences and methods have been accumulated, and valuable experience and technical support have been given for encountering similar situations in the future.
