一年来,我局使用无线电波坑道透视仪先后探测了十五个工作面,取得了显著效果。如在义井矿1441工作面准确地判断出落差4.6米的断层及其在工作面中的延伸位置;在王凤矿测出了贯穿整个1620工作面、落差9米的较大断层和1834、1851工作面中的隐伏构造—5条落差为0.8米左右的断层等,从而提高了矿井地质工作的质量,有力地指导了采掘生产的顺利进行。 在坑道透视工作中,首要的问题是做好“条件试验”,求得理论场强值,从而以此作为标准,用以衡量不同地点发射所
Over the past year, our bureau has used radio wave tunnel perspective instrument successively detected fifteen facets and achieved remarkable results. For example, in the 1441 face of Yi Jing Mine, the fault with a 4.6-meter drop and its extension in the face are accurately judged. In Wangfeng Mine, a large fault with a drop of 9 meters and a large fault of 1834, 1851 hidden face in the structure -5 drops of about 0.8 meters of fault, etc., thereby enhancing the quality of mine geological work, effectively guide the smooth progress of mining production. In the work of tunneling, the most important issue is to do a “conditional test” to find the theoretical field strength, so that it can be used as a standard to measure the different locations of launch sites
