Ha Long Coal: Promoting the Effectiveness of Science and Technology Application

10/12/2021

As a large-scale underground coal producer of Vietnam Coal and Mineral Industries Group (TKV), Ha Long Coal Company has had many solutions to promote the application of science and technology, implement mechanization to increase labor productivity, improve working conditions, and ensure safety for workers. In which, the M&E Workshop in Tan Lap area is considered as one of the leading units in promoting innovation and rationalization in production.

Promote mechanization in underground mining

Implementing the policy and direction of TKV Group on the program of “3 digitization” – mechanization, automation, computerization, in the process of production management and administration, Ha Long Coal Company has strengthened research and deploy application of automation, computerization and especially actively promote the implementation of CGH in underground mining. The light-weight synchronous mechanized furnace with a capacity of 300,000 tons/year applied at Ha Long Coal on August 15, 2020 is one of the first light-weight synchronous CGH furnaces of TKV and one of the 10 projects was selected by the Quang Ninh Provincial Party Committee to attach a sign to welcome the 15th Quang Ninh Provincial Party Congress, term 2020 – 2025.

The mechanized market furnace consists of 80 sets of self-propelled anti-rigs, 01 rake, 01 coal excavator, designed capacity of 300,000 tons of coal/year. When put into operation, the average output is 812 tons/day (an increase of 2.1 times compared to single hydraulic technology), the average labor productivity is 12.5 tons/ton (an increase of 2.9 times compared to that of single hydraulic technology). After more than 1 year of operation, the market furnace operates stably, workers fully master technology and equipment.

The introduction of light-weight synchronous mechanized kilns into production will save 30% of labor, improve productivity, improve working conditions, and ensure safety in the mining process. This is the biggest breakthrough in the application of science and technology in underground coal mining ever of the Company, creating a premise for enterprises to apply more mechanized furnaces in other seams. .

In order to reduce travel time for workers, the Company has put into use a cable car winch system with a total investment of nearly 15 billion VND. The cable car winch system has the function of transport workers positions from the ground to the tunnel, reducing the waiting time at the beginning and the end of the shift, increasing the useful working time in the production shifts, improving the traveling, ensure the health of workers.

Promoting technical innovations

At Ha Long Coal Company, the Electromechanical Workshop has the role of processing and repairing electromechanical and mechanical equipment, serving the operation of power stations, pumping stations, compressed air stations… In addition, the workshop also preserves, maintenance of safety and labor protection equipment, such as: Dispensing furnace lights, self-rescue bottles… With the assigned tasks, over the years, the M&E Workshop has always completed its tasks well and rose up. become the leading unit of Ha Long Coal Company in the movements of promoting technical innovation initiatives, applying them to production activities with high efficiency. On average, each year, the M&E Workshop in Tan Lap area has 7-10 initiatives to apply science and technology and rationalize production. From 2020 up to now, the workshop has had many initiatives that have been effectively applied in production, such as: Researching and manufacturing smart hangers for lifting the hydraulic column on top of the column remover; Processing and installing misting systems for industrial fans at MB+17 factory; processing, installing additional coarse dust filter in front of the air filter core of the LS-160 air compressor; Renovating and installing inverters to control and operate the V45 extractor, serving to squeeze workwear for workers working in the underground mines of Tan Lap area; Processing of pre-assembled gates to seal environmental lake overflows; install boot washing system…

In which, the successful research and manufacture of a smart hanger to serve to put the hydraulic column on top of the column remover applied for production at the MB+17 hydraulic anti-hydraulic test station in Tan Lap area has saved and taken advantage of materials are available in the workshop to make new products, helping the workshop to release heavy labor (workers do not have to carry pillars), improve working conditions and improve labor productivity and safety during production.

The initiative to process and install additional coarse dust filters in front of the air filter core of the LS-160 air compressor takes advantage of available materials in Tan Lap area to create a bag-type filter, made of fine fabric, sewn and shaped to suit the outside of the metal mesh core, ensuring firmness and filtering the coarse dust particles in the air, helping the workshop to save the cost of regular repair of the LS-160 air compressor; improve working efficiency, prolong the life of machinery and equipment; Limit interruptions in compressed air service.

The M&E Workshop’s initiatives are highly by the Company’s leaders, and have been making important contributions to helping the unit complete assigned tasks, thus improving working conditions, increasing productivity and income for employees, making an important contribution to helping the Company successfully realize its production and business goals in the first nine months of 2021, exploiting more than 1.46 million tons of coal, reaching 86% of the year plan; consumed more than 1.45 million tons of coal, reaching 89% of the year plan.

In the last months of the year, Ha Long Coal will continue to maintain effective measures to prevent the Covid-19 epidemic in accordance with the direction of Vinacomin and Quang Ninh province; at the same time organize flexible production management; strengthen technical management, safety, cost management; continue to promote and bring into play the efficiency of mechanization, automation, and computerization, attach importance to the application of new technologies, improve production capacity and efficiency of production and business, strive to complete the following tasks: planned targets in 2021.
