In 2010, Institute of Mining Science and Technology (IMSAT) had been assigned to carry out the theme “Study on the pilot application of the mining and driving technology using the domestic explosion-proof non – electrical delay detonators” and the theme “Study on the manufacture of the safety underground non – electrical delay detonators and its application with the long borehole blasting technology at underground coal mines in Quang Ninh coal basin”. The key aim of two above themes is to study on the pilot manufacture of the safety non – electrical delay detonators in Vietnam for its application with the long borehole blasting technology to increase the efficiency in slope coal seam mining and driving works<\/span><\/p>\n

According to the plan for Vietnam coal sector development in the period of 2010 – 2020 and forwards to the year of 2030, besides the improvement and increase the mining capacity of the existing coal mines, the coal sector has to invest in exploration, design, construction and extraction of 18 new coal mines and many of them will be opened with vertical shafts. Therefore, the number of vertical shafts serving the mining works at new mines at the coming period will be great, from 45 to 60 ones, as estimated.<\/span><\/p>\n

All coal seams at Quang Ninh coal basin have been formed in specific deposits. The rock layers have been classified from the fine-grained structures to the coarse grained ones. Therefore, the rock breaking process with combine can not be done with high efficiency due to the technological and technical characteristics of rocks. In this paper, the authors refer to some problems in driving works as well as the solutions that have been applied for increasing the driving speed at some underground coal mines.<\/span><\/p>\n

Na Rua iron ore mine is one of the mines having great reserves belonging Mineral Corporation. At the mine, there are two regions including the North and the South. The North region is the place with main distributed reserves of the mine with the overburden thickness of 70m. The mine is close to Cao Bang town, so that there have some public building constructions and residential areas on the mining field. Therefore, it is necessary to have technical mining solutions for ensuring annual mining capacity and safety for the surrounding building constructions<\/span><\/p>\n

In recent years, coal mining output in Vinacomin has rapidly increased. According to the development plan, the annual coal output in 2015 will reach to 60\u00a0\u00b8\u00a065 million tons, in 2020 will be 70\u00a0\u00b8\u00a075 million tons and in 2025 will be more than 80 million tons.

Tan Rai bauxite separation plant was constructed in 2010 with the annual capacity of 1,779,050 tons of concentrates, supplying to the alumina plant. To the year of 2012, all the production line at the plant has been put into the test run under load and no load and technologically adjusted, so far, more than 200,000 tons of concentrates has been produced. However, the classification efficiency at the screening link is low, not meeting the designed requirements. In this paper, the authors introduce some research results on the increase of the efficiency of the rotary screen in the flowsheet at Tan Rai bauxite separation plant carried out by Institute of Mining Science and Technology (IMSAT)<\/span><\/p>\n

According to the plan for the coal sector development approved by the Prime Minister, for ensuring the coal demands for our country s industrialization and modernization cause, the coal sector has increased the mining capacity of the open pit coal mines and opened new underground coal mines, especially carried out the underground coal mines underneath the open pit ones with inside dumpsites. Therefore, ensuring the labor safety and preventing the water breakout in the underground mining process is considered as an important task and paid much attention to<\/span><\/p>\n

At Lao Cai copper refining plant, there have been two water spray systems for the dust suppression installed by Chinese experts. However, these systems have not yet operated due to the inactive control equipment. Basing on the requirements from the restoration of these systems, in the year of 2011, Institute of Mining Science and Technology (IMSAT) had coordinated with the Lao Cai copper refining Company in study and evaluation of the feasibility conditions for providing the solutions for restoring, improving and controlling the Distributed Control System (DCS) in the plant<\/span><\/p>\n
