Blasting agent - Any material consisting of a mixture of a fuel and an oxidizer. It was estimated that even after 25 years of production of all the natural gas deemed recoverable, only 15 to 40 percent of the investment would be recouped.
Sloughing - The slow crumbling and falling away of material from roof, rib, and face.
Plan - A map showing features such as mine workings or geological structures on a horizontal plane. Respirable dust sample - A sample collected with an approved coal mine dust sampler unit attached to a miner, or so positioned as to measure the concentration of respirable dust to which the miner is exposed, and operated continuously over an entire work shift of such miner.
Volatile matter - The gaseous part, mostly hydrocarbons, of coal. Underground mine — Also known as a "deep" mine. Strike - The direction of the line of intersection of a bed or vein with the horizontal plane. In either type of conveyor it consists of a frame and either a sprocket or a drum on which the chain or belt travels, plus such other devices as may be required for adjusting belt or chain tension.
An overview of analytical methods for RTA is then provided, including a discussion of how these techniques can be modified to account for unconventional reservoir properties such as multi-phase flow, non-static permeability, non-Darcy flow, and desorption.
Bit - The hardened and strengthened device at the end of a drill rod that transmits the energy of breakage to the rock. The opposite of anticline. Suspension - Weaker strata hanging from stronger, overlying strata by means of roof bolts. Man trip - A carrier of mine personnel, by rail or rubber tire, to and from the work area.
Beginning level concepts are covered and widely focused enough to appeal to a broad audience seeking an introduction to the business of heavy oil including non-technical administrative and business groups.
Secondary inclined opening, driven upward to connect levels, sometimes on the dip of a deposit; also called "inclined shaft". Seam - A stratum or bed of coal. Preparation plant - A place where coal is cleaned, sized, and prepared for market.
Layout - The design or pattern of the main roadways and workings. Extraction - The process of mining and removal of cal or ore from a mine.
Sandstone - A sedimentary rock consisting of quartz sand united by some cementing material, such as iron oxide or calcium carbonate. In the s, a proposal was suggested for a modified in situ shale oil extraction process which involved creation of a rubble chimney a zone in the oil shale formation created by breaking the rock into fragments using a nuclear explosive.
Pyrite - A hard, heavy, shiny, yellow mineral, FeS2 or iron disulfide, generally in cubic crystals. The slow down in the production of nuclear weapons, beginning in the late s in the US, greatly impacted on the economic calculations of peaceful uses of nuclear detonations.
Using the same sample 1 gram under controlled heating at fixed temperatures and time periods, moisture, volatile matter, fixed carbon and ash content are successfully determined. Descriptive of certain rocks and minerals. Cycle mining - A system of mining in more than one working place at a time, that is, a miner takes a lift from the face and moves to another face while permanent roof support is established in the previous working face.
The next blast, a kiloton detonation at Yucca Flat, Nevada, displaced 12 million tons of soil and resulted in a radioactive dust cloud that rose 12, feet and plumed toward the Mississippi River.
Hydraulic control refers to the mechanical control of various parts of machines, such as coal cutters, loaders, etc.
Methane monitor - An electronic instrument often mounted on a piece of mining equipment, that detects and measures the methane content of mine air. Petroleum Risk and Decision Analysis Basic Level 16 Weeks Duration Description Good technical and business decisions are based on competent analysis of project costs, benefits and risks.
Tension - The act of stretching.
The fault zone consists of numerous interlacing small faults or a confused zone of gouge, breccia, or mylonite. The vertical transport of the same is called hoisting.
We have provided water boreholes in various Rural Communities, fitted with environmentally friendly solar pumps, to supply reliable irrigation for vegetable gardens and drinkable water for households.
Applied to a rock, soil, or fossil when occurring in the situation in which it was originally formed or deposited. Severance — The separation of a mineral interest from other interests in the land by grant or reservation.
Coal mine - An area of land and all structures, facilities, machinery, tools, equipment, shafts, slopes, tunnels, excavations, and other property, real or personal, placed upon, under, or above the surface of such land by any person, used in extracting coal from its natural deposits in the earth by any means or method, and the work of preparing the coal so extracted, including coal preparation facilities.
Cap - A miner's safety helmet.
Roof sag - The sinking, bending, or curving of the roof, especially in the middle, from weight or pressure. Belt idler - A roller, usually of cylindrical shape, which is supported on a frame and which, in turn, supports or guides a conveyor belt.
The Explosives Branch agrees to allocate time for selected WorkSafeBC prevention officers to present the requirements of the Regulation during training programs conducted in British Columbia for the subject industries.
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
