Product development

In terms of research and development of underground trackless equipment: In 14 years, we have developed from the initial three models to more than 30 models. We have won about 65 award-winning scientific research results and renovation projects, and have no less than 100 technological improvements. In the design of the driving system, work steering system, braking system and control system, closely combining the technical capabilities and on-site working conditions of various mine operators and maintenance personnel, the unique characteristics of the product have been developed, and the practical process of domestic and foreign products has been fully used for reference. In practice experience, continuous improvement and innovation are formed. Development positioning: the underground scraper series reach 10m³; the underground mining truck series reach 50 tons; accelerate the development process of rock drilling rigs and bolting rigs. In addition to more in-depth research on intelligent products and intelligent control systems, the research on pure electric scrapers and mining trucks has begun. Take data, intelligence, and flexibility as the standard for product research and development goals, research and develop one generation, prepare one generation, and mass produce one generation. First-class processing, manufacturing, inspection and testing equipment will help comprehensively improve scientific research, development, and production capabilities. We will continue to develop and manufacture high-efficiency, energy-saving, safe, and environmentally-friendly new products based on the needs of mines, and gradually develop in the direction of high-quality, refined quality, and cutting-edge technology, so as to be domestically first-class and catch up with international standards. Contribute to the localization of underground trackless equipment and the improvement of quality and efficiency of mines.

 

With regard to the development of intelligent tailings filling equipment: With the group’s policy-oriented construction of tailings-free mines and green mines, under the promotion of leaders of the group, Yantai business department and the company at all levels, a strategic cooperation agreement was signed with the filling engineering laboratory of Shandong Gold Group. And hire a professor from Central South University to do technical guidance. The successful development of intelligent tailings filling equipment has opened up a new path for the comprehensive utilization of tailings, provided technical and equipment support for the construction of tailings-free mines, and also escorted the construction of Shandong gold and even the national green mines. Development orientation: Adhere to customer demand as the orientation, devote itself to solving substantive problems in the production and operation of mining enterprises, and carry out technological innovation and optimization of traditional products. The completed technological innovations mainly include 25m³ circular flotation machine, 4 cubic closed flotation machine, 2 cubic light wear-resistant mining cart, 15m hydraulic center drive high-efficiency thickener, etc. A total of 9 technical innovation achievements of the group have been declared, of which 1 item Won the third prize of scientific and technological progress, 7 of them won the first, second, and third prizes of technological innovation, 2 utility model patents have been accepted, and another patent is being filed. Through technological innovation, the technical content of the product has been increased, and the added value and market competitiveness of the product have been improved.

 

Product technical performance positioning:

 

(1) High-end demand

For example, Sanshan Island, Jiaojia, Xincheng, Laixi Mining, etc., automated and intelligent supporting hard power and system maintenance soft power have reached a certain level, and there will be high-end demand for products.

Product technical performance positioning: high-end high-profile, high electro-hydraulic control and intelligent control.

Progress made in intelligent control technology

In 2019, we completed the research and development of two 5G scene over-the-horizon scrapers: one is the "1m³ over-the-horizon control electric scraper" developed for Laixi Mining, and it is the world's first remote control based on 5G scenarios. Control the scraper. One is the "3m³ over-the-horizon internal combustion scraper" developed for the Jiaojia Gold Mine, which is two representative models.

The main problems solved by the application of 5G technology in the field of underground trackless equipment:

1. The transmission rate is higher, and the time delay is low, theoretically reaching 10ms, and reaching about 20ms from the surface to the underground.

2. The performance of wide connection can meet the network transmission requirements of multiple equipment operations.

3. Stronger anti-interference ability

(2) Positioning of mid-range demand products

Most customers still focus on the demand for mid-range products. This part of the customer group is: state-owned mining enterprises with relatively complete management; use of underground trackless equipment for long-term reconstruction and expansion of mining enterprises; enterprises with incomplete intelligent automation supporting facilities, and relatively weak maintenance teams and maintenance capabilities.

The mid-end demand product is positioned as the configuration is still high-end and high-end, but the control system mainly adopts mechanical control, hydraulic control or electro-hydraulic control.

At present, from the perspective of market share, customer demand for mid-range products still occupies the majority

 

2. New product development and new technology research positioning

New product development:

The scraper is developing towards the large-scale bucket capacity of 6-10m³ to open up the mining market in the non-gold field; the mining truck plans to develop 25 to 30 tons of products.

Started the development of the fourth series of products such as rock drilling, bolts and shotcrete, and completed mass production during the "14th Five-Year Plan" period.

Technical research direction:

In addition to more in-depth research on intelligent products and intelligent control systems, the research on pure electric scrapers and mining trucks has begun.
