Our company has always attached great importance to technological innovation, continuously increasing technological investment and product research and development efforts. Having comprehensive and sustainable original innovation capabilities, possessing independent intellectual property rights, and obtaining 9 national invention patents and 54 utility model patents; The "inherently safe" grouting reinforcement material with low reaction temperature, non combustible and non reactive with water is our company's first conceptual application technology.

As the largest non-metallic polymer material development and manufacturing service provider for coal mine safety in China, the domestic market share has always maintained a leading position in recent years. The company's products have filled in and changed the concept of coal mine safety technology, and have been widely used in National Energy Group, China coal Energy, Shandong Energy Group, Jinneng Group, China Datang Energy, China Huarun Group, Huadian Group, Huaneng Group, Shan Coal Group, Shanxi Coking Coal, Yongtai Energy, Henan Energy Group, Guizhou Energy Group, Huayang Group, Lu'an Chemical, Huainan Mining, Pingmei Shenma Group, Lanhua Group, Jining Energy more than 60 coal enterprises and over 400 mines. And we have established cooperative relationships with non coal enterprises such as China Railway, China Construction Corporation, China Communications Corporation, China Electric Power Construction Corporation, China Gold, Shandong Gold, and Jinchuan Group, further expanding the non coal product market. Participated in national key projects such as the Yaxia Railway, the Hong Kong Zhuhai Macao Bridge, and the Han River to Wei River diversion project, and gained good reputation.

To stay close to the site of the mine, our company has established a technical service team of over 50 people to provide on-site services nationwide. Our company's chemical material products are not only used as safety guarantees for daily safety production in mines, but have also actively participated in emergency rescue and rescue of mines nationwide in accordance with the instructions and requirements of the State Administration of Work Safety and leaders of safety supervision departments at all levels for many years, including Xinji Second Mine, National Energy Bulianta Mine, Ning Coal Jinjiaqu, Xinjiang Shajihai Mine, Qinghai Haibei Prefecture Chaidar Mine, Datong Tashan Mine, Inner Mongolia Camel Mine Emergency rescue work for large-scale roof fall, water inrush, and fire accidents in Mengxin Expressway Tunnel, Xiamen Xiang'an Submarine Tunnel, Datong Silaogou Coal Mine, Zaozhuang Preparedness Mine, Xinzhuang Mine, and other mining areas. I also participated in post disaster reconstruction work in Xingtai Dongpang, Tongchuan Chenjiashan, Zhengzhou Chaohua, Hebi No.2 Mine, Fuxin Haizhou Shaft, and other mining areas.

In addition to providing direct research and development, production, and service to customers, our company, as a leader in the mining polymer material industry, actively assists and participates in the standardized management of the mining polymer material industry. In 2008, according to the standard preparation plan project arrangement of the State Administration of Work Safety, our company organized the preparation of four industry standards: AQ 1089-2011 "Polymer Materials for Strengthening Coal and Rock in Coal Mines", AQ 1087-2011 "Technical Conditions for Polymer Materials for Water Blocking in Coal Mines", AQ 1090-2011 "Technical Conditions for Polymer Foam Materials for Filling and Sealing in Coal Mines", and AQ 1088-2011 "Technical Conditions for Polymer Materials for Spray Sealing in Coal Mines", The first standardization meeting was held in August 2011 and was implemented on December 1, 2011.

With the continuous progress of polymer material technology for coal mine grouting and the increasing requirements of coal mine safety production for polymer material technology for coal mine grouting, in 2012, 2014, and 2015, our company successively obtained one drafting plan and three modification plans from the State Administration of Work Safety, which are classified as AQ 1117-2020 "Management Specification for Safe Use of Polymer Materials for Coal Mine Underground Grouting" ,AQT 1089-2020 "Polyurethane Materials for Strengthening Coal and Rock Masses in Coal Mines", AQT 1090-2020 "Polymer Materials for Filling and Sealing Coal Mines", and AQT 1087-2020 "Polymer Materials for Water Blocking in Coal Mines" , were all implemented on May 1, 2021.

In 2017, in accordance with the conclusions of the inter-ministerial joint meeting of the Standardization Committee of the State Council on the integration of mandatory standards, our company obtained a project plan to integrate and draft the national mandatory standard "General Safety Technical Specification for Polymer Materials for Coal Mine Underground Grouting and Spraying" and a project plan to modify the industry standard "Polymer Materials for Coal Mine Spraying and Sealing Air", both of which are ongoing. In the process of preparing national standard projects, our company drafted the transitional standard AQ1116-2020 "General Safety Technical Specification for Polymer Materials for Coal Mine Reinforcement, Water Blocking, Filling, and Spraying", which was implemented on May 1, 2021. Our company is also participating in the drafting of one national standard for "Accelerating for Spraying Concrete", one product standard for reinforced filter screens in highway engineering, and six geological disaster prevention and control standards of the Ministry of Land and Resources.

The company's advanced products have filled the gap in polymer chemical products in domestic coal mines, and were the first to promote the use of polymer chemical grouting products to solve coal mine safety problems in China. And on the basis of extensive practice, we have continuously improved product performance and expanded our product range. For coal mine safety and efficient production, we have developed more than 10 series of over 50 proprietary products.

In order to improve the company's technological content and enhance market competitiveness, we have collaborated with Shandong University to establish the "Shanda HOCK Geotechnical Engineering Groundwater Sealing and Reinforcement Technology Research Institute" and "Advanced Civil Engineering Technology and Industry Research Institute". We have also collaborated with China University of Mining and Technology to establish the "China Mining HOCK Rock Stratum Control Research Institute", as well as with the General Institute of Coal Science Research and China Railway Tunnel Science Research Institute Wuhan Institute of Geotechnical Mechanics, Chinese Academy of Sciences, Beijing University of Chemical Technology and other scientific research institutes have maintained long-term and stable cooperative relations. We have provided strong idea support in developing new products, researching new technologies, expanding new material applications, and maintaining the company's leading position in the polymer grouting material market.
