Cao Son Coal: Promotes production innovation

Shortening the supply road for transporting soil and rock to landfills, improving labor productivity, contributing to increase revenue by up to 30% is the results achieved by Cao Son Coal Joint Stock Company thanks to technological innovation and promoting innovation (kaizen) into production and business.

In 2019, Cao Son Coal Joint Stock Company was assigned the largest target ever by Vietnam National Coal-Mineral Industries Group (TKV) with the volume of excavation, shoveling and transporting 35.7 million cubic meters of rock and soil; producing 3.8 million tons of coal of all kinds; coal consumed 3.7 million tons, revenue increased 30% compared to the plan in 2018.

In order to ensure the implementation of the above targets and tasks, the Trade Union of the company has actively participated, promoting the effective labor emulation movement, encouraging enthusiastic workers to participate, etc. Especially, in May – the peak month of emulation, the whole company has 15 projects registered to solve problems due to the independent trade union or joint venture completed, bringing high economic efficiency in production and business. Typically, such works are renovating and opening up the +20 transport route, contributing to shortening the supply of rock and soil to the 1.5km dump of the Union of Exploitation Workplace I; works to accelerate the maintenance and repair of equipment of Trade Union parts of Transport Workshop 3, 4, 7; environmental sanitation works for the cafeteria areas of the Life Workshop Union; together with 20 technical innovations, rationalizing production.

In addition, realizing that the old and degraded system of machinery affects the production progress, the company invested in buying a hydraulic MD rotary drilling rig MD6250 (US technology), in order to restore the Services for open-pit mining and blasting operations. The new drill is capable of drilling at a maximum depth of 54m instead of 32m as the old stock machine, so after a period of use, the company has improved the exploitation output and significantly saved human resources. In particular, the new drill also has many advanced technology features such as data connectivity, software updates to track drill hours, fuel amount, accuracy of the drill reach 100%. Many stages of manipulating the drill were automated, so that the company reduced the labor from 3 people to 2 people compared to when operating the old drill.

At the same time, the company is also equipped with a GPS-based management system combined with fuel sensors for 245 mining and transporting equipment using diesel fuel. Invest in 4 high-pressure nebulizers to prevent dust; automatic application of local dust pump operation control; investing in technological innovation, renewing equipment in the main stages, investing in new equipment in transporting coal, excavators and drilling machines. Thanks to that, the exploitation as well as the operation is smooth, the effect is increasingly clear.

These efforts have contributed positively to the company’s business results. The targets all met and exceeded the plan assigned by TKV. In particular, a monthly record of over 4 million cubic meters of rock and soil has been established; total coal production: 4,073 million tons = 123% in 2018, an increase of 5.9% compared to the year plan; coal consumption reached 4,005,120 tons = 130% in 2018; coal revenue VND 5,758 billion = 192% of the plan; the average coal output will reach 1,653 tons / person; Average salary reached 11 million / person / month, equal to 127% of the plan and 113% of the implementation compared to 2018.
