Aoki Mining Co., Ltd., which has a quarry representing Hokkaido History In 1963, Aoki Mining started the crushed stone industry with permission to mine andesite in the Sapporo Business Zone of the Sapporo Forestry Office. The company name "Mine" comes from the fact that the company's predecessor was engaged in coal mine development in Rumoi City, Hokkaido until 1959. "At that time, for example, foreign coal that came into Tomakomai was about 4,000 yen tons, but if you bring domestic coal to Tomakomai, there is a price difference of about 6,000 yen and 2,000 yen, and the coal industry is becoming more and more obscure. Therefore, because it was an industry that could make use of the technology that had been cultivated up to that point, such as rupture work, the stone color was different, but it was converted to the crushing industry "(President Aoki). The Sapporo Factory (2-3-6-1, Minamisawa, Minami-ku, Sapporo) was opened in 1963, and the Fukagawa Factory (562, Koyo, Otoe-cho, Fukagawa) was opened in 1973. Manufactures various types of crushed stone and sand for roads and concrete (Fukagawa Factory). At the peak, the combined annual production of both plants reached about 600,000 tons. The Sapporo factory was transferred to Sumitomo Coal Mining Co., Ltd. in 2000. Fukagawa Factory: Hokkaido's first mountain crushed stone JIS factory Otoe-cho, Fukagawa City, where the Fukagawa Factory is located, is a transportation hub with a station on the Kamikawa Road (currently National Route 12), which was created for the development of Kamikawa (Asahikawa) in 1890. In addition, there are many major arteries in Hokkaido such as the Hokkaido Expressway and the Hakodate Main Line. The rock type of the rough stone mountain of the factory is pyroxene andesite. Due to its high quality stone quality, it is heavily used for highway construction, etc., and the entire amount of crushed stone for pavement, which is approximately 84 km between the Mikasa IC and Takasu IC on the Hokkaido Expressway, was delivered from the factory. Currently, in addition to roads, 150,000 to 200,000 m3 of crushed stone and crushed sand for ready-mixed concrete are manufactured annually. In addition to working to improve quality for high-performance pavement, "I try to find waste by walking in the factory as much as possible, and I am focusing on automation and energy saving," said President Aoki. In December 1974, it was the first mountain crushed stone in Hokkaido to obtain a permit from a concrete crushed stone JIS display factory. "Whether it was the Sapporo Factory or the Fukagawa Factory, it was easy to deliver to the city, roads, and the Development Bureau, but the standards are very strict on expressways. Therefore, it is higher than the roadbed construction. In order to make employees aware that all items and size items have the JIS mark on the slips, we obtained JIS at both factories. By doing so, we test every 500 m3, so there is at least one person. It is necessary, and if there is a problem, it will be our responsibility. However, the price does not change, but I think it is a credit problem that cannot be converted into money.
