一、概述 WKT—JⅠ、JⅡ型无线电波坑道透视仪(简称坑透仪),自1976年鉴定使用以来,在全国许多局、矿得到推广、普及,成为我国第一件在煤矿井下使用的非防爆型矿井物探设备。实践证明,坑透仪及无线电波透视法适应了我国煤矿机械化、综合机械化发展形势的需要,为保证采煤工作面回采的顺利进行,探明工作面内陷落柱、
I. Overview WKT-J Ⅰ, J Ⅱ radio wave tunnel perspective instrument (referred to as pit instrument), since the identification of the use since 1976, many in the country, the mine has been promoted, universal, as China's first use of non-coal mine in the non- Explosion-proof mine geophysical equipment. Practice has proved that the pit through instrument and radio wave perspective method to adapt to the mechanization of coal mines in China, the needs of the situation of the development of mechanization, coal mining face to ensure the smooth progress of recovery, proven work surface collapse column,
