Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as blast furnaces consist of several zones: a crucibleshaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) .
Tin mining is one of the earliest type of mining operated in Malaysia, starting in the 1820s in Perak and in 1824 in Selangor. The development of mining industries in Malaysia attracted many Chinese immigrants who came to the state in 18th and 19th centuries to work and develop the mine fields. The majority of Malayan tin mined prior to the Second World War was being .

Coal dust is a fine powdered form of which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier .

· Modified Hartmann and 1m 3 explosion vessels were used to perform flame speed and explosion tests. Finesized particles propagated the flame with a flame velocity of m/s for nonsphericalshaped particles compared to roundshaped lycopodium and corn flour. For coarse size particles, the flame speeds were measured to be around 1 m/s.

· Directional drilling is a broad term used to describe any boring that doesn't go in a straight line vertically down. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. In this instance, the driller uses sidetracking techniques.
When a spark or other ignition source ignites in a vessel, a fireball develops as the material burns and grows at an exponential pace, often within milliseconds. The pressure expands rapidly as the fireball grows, reaching the explosion vent. The explosion vent opens at a specified pressure, dictated by the type of vent equipped by the vessel.
all played an important role in reducing the occurrence of explosions in this industry, as well as mitigating their effects. The lessons learned in the grain industry can be applied to other industries producing, generating, or using combustible dust. Elements of a Dust Explosion . Elements Needed for a Fire (the familiar "Fire Triangle"): 1.
(ii) Vertical tubular. (a) Straight vertical shell, vertical tube (b) Cochran (vertical shell) horizontal tube. Various advantages of fire tube boilers are as follows. (i) Low cost (ii) Fluctuations of steam demand can be met easily (iii) It is compact in size. FireTube Boiler This boiler consists of a cylindrical shell with its crown ...

· 2. South Kalimantan. 3. East Kalimantan. The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions (mainly in Sumatra and Kalimantan). Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust ...
