一、序言 我局于1978年初开始应用wkT—J_1和J_2型坑道透视仪探测采面的异常地质构造。两年来,先后在二、三、四、五、牛儿庄、薛村、孙庄矿等7个矿,大煤、一座、野青、山青、小青等5个可采煤层i6个工作面进行了试测,其中7个采面已经回采。在这7个采面中发现的8个地质异常区,有7个得到了证实,说明用坑透法探测采面的异常地质构造,是较为有效的一种手段。 二、工作方法 在井下工作时,发射机和接收机分别置于上、下顺槽中。发射机固定在预先设
First, the preface Our bureau in early 1978 began to use wkT-J_1 and J_2 tunnel perspective detection of abnormal geological face. In the past two years, seven coal mines, one coal, one wild grass, one green hill, one small hill and five other coal seams have been successively built in seamounts of 6, 3, 4, The working face was tested, of which 7 mining face has been mining. Seven of the eight geological anomalies found in the seven facets have been confirmed, indicating that it is an effective method to detect the abnormal geological structure of the mining face by the pit penetration method. Second, working methods In the downhole work, the transmitter and receiver were placed in the upper and lower cis slot. The transmitter is fixed in advance
