Hachinohe Smelting Company was established on Feb. 1st, 1967 as a joint toll smelter to take advantage of the Imperial Smelting Process to treat mixed and complex ores, especially some concentrates from “black ore” in Tohoku district of Japan and concentrates from Huanzala Mine in Peru. The Hachinohe ISF plant was commissioned in Feb., 1967, and has beensu ccessfully operating with excellent performances.The Smelter Complex consists of sinter plant, acid plant, furnace plant, and zinc refinery. The sinter plant employs the Lurgi type sintering machine, while acid is produced in Lurgi type double contact acid plant. Some parts of crude zinc producedb y the ISF is further refined by its own reflux ing refining plant. Bullion is shipped without refining.Since the, operation commencement, various improvements and modifications have been constantly applied to make the plant competitive, emphasizing the theme of “conservation and recovery of energy”. A typical example of the efforts is incorporation of power generator which utilizes waste heat of the furnace off-gas. Now the plant is trying to further strengthen its ability to cope with low production.rate forced by current unfavorable situations surrounding zinc industry

The deposits of this mine lie in or along the faults as replacement and impregnation. So, generally speaking, it is very difficult to distinguish the boundaries between ore bodies and country rocks. Moreover, the both sides of ore bodies are very brittle due to shearing stress and alteration of rock. Therefore, timbering and filling with waste rock are necessary in stoping. Until recently the over land flatback filled stoping had been used, but the slushers has been adopted in filled stopes, since June 1956, to raise the efficiency of stoping. The results of slushers in filled stopes have been a great success.

According to the increasing output plan, construction of the new coal preparation plant of 400 tons per hour in capacity had been projected at Mitsubishi-Bibai Colliery, Hokkaido. The new plant construction was started in February 1960 and was put in operation in June 1961. For the purpose of high efficiency in cleaning and accurate stability in coal quality, the new plant adopted Drewboy dense-medium separators for, coarse coal and a feldspar bed-jig for fine coal.This paper describes chiefly the fundamental elements and some problems involved in the design of the new plant as well as its outlines.

Matsumine deposit, located in the northern part of Odate basin, Akita Prefecture, is a large scale Kuroko deposit. This deposit was discovered in 1963. The development work was started in July 1964, and the production was started in October 1966, at the rate of 20, 000 tons/month. Current production rate is 40, 000 tons/month, and it is the largest copper supplier in Japan.The Kuroko generally consists of black ore, yellow ore (cupriferous pyrite ore) and siliceous ore. The black ore (Kuroko) is a black coloured ore consisting mainly of sphalerite, garena and barite, and rich in gold and silver, too. The yellow ore is a yellow massive powdery ore comprising mainly chalcopyrite and pyrite. The siliceous ore which is rich in silica is divided into two types, one containing considerable amount of chalcopyrite and pyrite, and the other with a high sphalerite content.The mining method applied is “The underhand cut and fill with artificial roofing”. Once a unit block of ore is mined out in a stope, iron reinforcing bars are laid on the floor, and a 15 percent cemented mortar mixed with mill tailings and volcanic ash is pumped over the bars up to 0.6 meter thickness. Then, the space above the layer is filled with the 3 percent cemented sand slime. This reinforced mortar serves as an artificial roof when ores below are mined next. In 1982, the conventional battery locomotive and tub system was partly replaced by the trackless system with L. H. D.

As in about ten years the new mining machines and technics were imported, the mining method in Japan were changed remarkably.Natural condition of coal seam in Japan (1956)Working depth (Average) 334.7m(Maximum) 836mAverage thickness of seam 1.71mAverage thickness of coal 1.31mOutput from coal face 48.281Mill. t.About 65% of output is worked by longwall method. About 36% of output is gotten by blasting, and 36% by coal picks in coal face, but coal cutters are used pretly well. Hobels are used in Emukae, Takashima, Kogayama and Mitsubishi-Bibai. 55% of output is conveyed Panzer conveyor at coal face.Hydraulic stowing is carried out at Onoura and pneumatic stowing is used at Yamano, Akabira and Sakito coal mines. Slicing method for thick seam is carried out at Hojo and Takashima coal mines.We must decrease the number of coal faces in one pit and increase the output per one coal face, and use the practical working time effectively.

The coal seam of Shikamachi coal mine, belonging to Hokusho district in Sasebo coal field, is thin, from 0.35 to 0.5 meter high, and soft. The coal of which is called strongly caking coal.Before, the stripping scraper was employed, hand-digging had been held only.We investigated and tested practicaly the stripping scraper as the mining machine that can be applied to the above conditional seam.Now we have used it practically.In this report, we describe simply about the following articles.1. Mechamizm of the stripping scraper.2. The state of operation in faces.3. The results.4. Comparison of efficiency between stripping scraper and hand-digging.

Sunagawa Colliery has managed to solve many difficult problems since 1914 and the technical innovation took place in 1964 when the colliery employed hydraulic mining. Subsequently, the hydraulic mining has been steadily improved widening the range of its application. The colliery is now working steeply inclined seams at the depth of 900 to 1000 meters below surface. The author intends to introduce parts of the results successfully practiced in the deep mining at Sunagawa Colliery.
