• VLF Electromagnetic Instrument is to utilize the electromagnetic wave transmitted by VLF radio station as field source to determine the changes of various parameters of VLF electromagnetic field under the influence of geologic body.
• Mainly used for detecting underground ore body and caves, and for rapid resistivity mapping; also has good prospecting effects on searching of underground pipes, water leakage of building foundations and collapse foundations.
• The instrument is compact in size and light in weight, easy for operation, with stable and reliable performance, multiple function with one machine, with flexible operating method.

Our factory, named as Chongqing Exploration Machinery Factory, was middle-size backbone enterprise of original Ministry of Geology and Mineral Resources. Nowadays, it is specialized by China Mechanical Group and China Geo-equipment Group in producing series of core drilling machine, series of anchor drilling machine, series of engineering drilling machine and directional drilling rig and hydraulic components.

The factory is located at culture area of Chongqing---the center of Shapingba district, has convenient communication and transportation, occupies more than 130,000 square meters in which there are more than 600 workers and staff (more than 100 engineers and technicians of them), has CAD center, capability to reseach and develop new products independently, has advanced technology, and perfect check means and equipment. We have successfully undertaken science and technology key programs which were allocated by State Science and Technology commission and original Ministry of Geology and Mineral Resources, such as XY-2 core drilling rig and MGJ-30 anchor drilling machine, which were awarded Science and Technology second grade by Ministry of Geology and Mineral Resources; GX-1TD was awarded third grade. Our factory is evaluated by China Quality Control Association as"USER SATISFIED ENTERPRISE", "AN ENTERPRISE WITHOUT ACCUSING OF QUALITY", "TRANS-CENTURY MODEL ENTERPRISE WITHOUT ACCUSING OF QUALITY".

Our factory have formed quite production scale through many years of development since immigrated into Chongqing form Shanghai in 1966, the produced product from single in first time of the factory founded to at present time more than 20 products of core drilling rig series, anchor drilling machine series and engineering drilling rig etc.. The products are sold well in more than 30 provinces, cities and autonomous regions and for more than 20 ministries and commission, also have large share of market in Hongkong and East-south Asia, and far sold to West Asia, Africa and South Europe etc., and enjoy high reputation and good fame in domestic and abroad.

The factory has got QUALITY MANAGEMENT SYSTEM CERTIFCATE OF ISO9001:2000 since 2002.

The whole staff seeking after best is always our purpose, our final goal is"ALWAYSLET CONSUMER SATISFIED".
