Introduction to the Tunlan Mine Disaster

Tunlan Mine and Coal Preparation Plant have strong production technical force and well-equipped equipment. They have internationally leading coal mining and washing and processing technology, and have built the first domestic supporting equipment with high mining height, high power and intelligence. chemical working surface. Equipped with a 35KV substation and a strong inclined shaft steel wire rope belt with a bandwidth of 1.4M and a transportation distance of 1000m. The fully mechanized mining working face is equipped with one set of domestic MGTY500/1200-3.3D electric traction shearers and two sets of MGTY250/600-1.1D electric traction shearers; the excavation working face is equipped with one set of S-200 type and four sets of S- Type 100 tunnel boring machine; the underground transportation is implemented with a belt, and the auxiliary transportation uses a 10-ton wired pulse-speed electric locomotive; an underground personnel monitoring and mobile communication system is installed and used. The coal preparation plant adopts the pressureless three-product heavy medium cyclone coal preparation production process. The main equipment such as cyclone, magnetic separator, pressurized filter, moving screen jig, flotation machine and centralized control system are respectively composed of Introduced from Germany and the United States, it has reached the international advanced level of similar products. The media test uses an online dust meter from Australia and electronic balances from Germany and Switzerland, which have reliable quality assurance methods. In 1999, the mine and its coal preparation plant simultaneously passed ISO-9002 quality system certification and ISO-14001 environmental management system certification.

As the brand mine and window unit of Shanxi Coking Coal Group Corporation, Tunlan Mine adheres to the goal of "strive to build a first-class modern mine in China", focusing on efficiency, surviving on quality, and developing on science and technology. Take the path of new industrialization and continuously improve the core competitiveness of enterprises. The mine's main products, "Xishan Brand" grade 10 and grade 9 coking coal, are provincial quality products and are mainly supplied to key national enterprises such as Baosteel, Shougang, and Handan Iron and Steel Co., Ltd., and some products have been exported to South Korea, Japan, Germany, Turkey, etc. Tunlan Mine adheres to the simultaneous planning, implementation, and development of spiritual civilization and material civilization, constantly innovates the form of activities, carries out creative activities that are popular among employees, and guides employees to pursue a scientific and healthy lifestyle; it adheres to the combination of comprehensive environmental management and greening and beautification. , strives to build garden-style mines, with a greening rate of 44.4, and has embarked on a development path with Tunlan characteristics in the construction of two civilizations in the mining area.

In 2006, Tunlan produced 4.68 million tons of raw coal, ranking first in Xishan coal-fired power generation. But there is no trace of "coal" in the mining area. All underground raw coal is transported in a closed manner, without being exposed to the open air or falling to the ground, and is 100% washed. Cleaned coal is shipped directly to customers via rail. A 500-meter-long coal pipeline transports washed coal, coal slime, coal gangue, etc., the by-products of coal preparation, to Gujiao Power Plant. All mining areas have achieved garden-style clean production. With an annual output of more than 4 million tons of raw coal, not a single piece of coal is bloody. Tunlan has maintained a record of zero mortality per million tons since 2004. The fundamental reason lies in technological progress. And here, "scientific and technological progress" is not simply "introduction" and "purchasing". Among the first-class intelligent equipment in the country, many are Tunlan’s independent intellectual property rights. For example, Tunlan is the first company in the world to use "large-section support" in coal mining. This project, developed by mine director Yin Gencheng and others, also won the "First Prize of the National Science and Technology Progress Award". In 2006 alone, the mine invested more than 10 million yuan in scientific research funds and applied for multiple national patents. In 2006, there was another piece of news about the mine that was widely publicized by the national media: "Migrant worker Duan Tanxi corrected illegal operations many times and avoided major accidents, and was commended and rewarded..." This is probably a good footnote for the construction of safety culture in the mine.

183 cubic meters of gas gush out every minute. In the eyes of Tunlan people, this is also a precious resource. In 2005, the mine invested 1.9 million yuan to transform coal-fired boilers into gas boilers, using 5 million cubic meters of gas every year and saving 10,000 tons of coal.
