In 2015, it was established to undertake all the assets, liabilities, personnel and business of the former Lianyungang Huanghai Machinery Co., Ltd., formerly known as the Northwest Exploration Machinery Factory of the Ministry of Geology and Mineral Resources established in Wushan County, Gansu Province in 1970. In 1995, the whole system was relocated to Lianyungang, Jiangsu Province. city.


Our products have been sold to 33 provinces, municipalities and autonomous regions, and exported to more than 40 countries and regions. From 2008 to 2014, we have been recognized as the national "leading enterprise in the manufacturing industry of special equipment for geological exploration" for seven consecutive years.

Lianyungang yellow sea exploration technology co., ltd. is a high-tech enterprise specializing in the development of geotechnical drilling equipment. In 2015, the company was established by undertaking all assets, liabilities, personnel and business of the former lianyungang yellow sea machinery co., LTD., formerly known as the northwest prospecting machinery factory of the ministry of geology and mineral resources established in wushan county, gansu province in 1970. In 1995, the whole construction system was relocated to lianyungang city, jiangsu province.


The company covers an area of 191400 square meters, construction area of 103700 square meters, production, testing equipment more than 450 sets, have structure welding, machining, heat treatment, painting, assembly, such as production capacity, is the larger scale of rock and soil drilling equipment manufacturing enterprises in our country, in a deep hole in the core drilling equipment, field of trenchless construction equipment has strong competitive advantage.


After 50 years of development, the company's leading products have four series of more than 80 varieties: a series of core drilling RIGS for 100-4200 meters deep solid deposit exploration and drilling, engineering geology and hydrogeology exploration, shallow oil and natural gas exploitation and mine tunnel ventilation and drainage, etc.; Multi-functional drilling RIGS for shale gas, coalbed methane drilling, shallow oil and gas drilling, oil well workover and geothermal well construction, and ultra-deep hole core exploration and drilling; A series of engineering drilling RIGS for drilling foundation pile holes of 0.8-3 meters in quaternary gravel bearing strata and hard strata, such as Bridges, highways and high-rise buildings; It is used for laying all kinds of pipelines (including power cable, telecommunication cable, heat pipe, gas pipe, drain pipe, etc.) and horizontal directional drilling machine with 150kn-15000kn backhaul force across rivers, highways, railways, buildings and other obstacles.


After 50 years of development, the company has a profound accumulation of industry knowledge and key technologies. "Key technologies and drilling rig series of high-performance all-hydraulic geological drilling rig" won the first prize of science and technology award of ministry of land and resources in 2013. The hxy-9b vertical shaft core drilling machine has completed the "first deep drilling of China's rock-gold exploration", with a final hole depth of 4,006.17 meters and a final hole diameter of 75 mm, which is a pioneer in domestic solid mineral exploration of small-bore core deep drilling. The directional crossing drilling rig, with a backhaul capacity of 1,000 tons, has successfully completed the project of qinbei Yellow River diversion irrigation area in jiaozuo city and the gas pipeline project of baodi - xianghe - xiji liaison line on the fourth line between shaanxi and Beijing.


In recent years, the company relies on the self-support, the agency two platforms, develops the domestic, the foreign two markets, the product marketing nationwide, and exports more than 40 countries and the region.


In the future, under the guidance of the enterprise spirit of "loyalty to the enterprise, love for employees, harmonious endeavor, and pursuit of excellence", we will strengthen and expand our enterprise down-to-earth. Make our products better and stronger; Persevering in the pursuit of drilling machinery in the yellow sea among the world.
