The USGS phosphorus filter is constructed with large tanks that each hold around six hundred pounds of granular mine drainage ochre and uses a gravity flow process where the phosphorus infused water is piped to the top of the tank, allowing it to pass through the porous ochre media, and the filtered water is released out the bottom of the tank.

Run of mine (ROM) coal production will come from multiple seams which have variable thicknesses across the mine lease area. Varying amounts of dilution will be present in the ROM. To produce a uniform product or products from the ROM, washability analysis has been undertaken which indicates that the seams contain low volatile hard coking coal.

Rock dust is not a fertilizer, for it lacks the qualifying levels of nitrogen, potassium, and phosphorus. Rockdust is also the limestone-based product sprayed on walls inside underground coal mines to keep coal dust levels down. This is to prevent coal dust explosions and also to prevent the incidence of black lung disease

Coal mining is further divided into Bituminous coal underground mining, Bituminous coal and lignite surface mining, and Anthracite mining. Bituminous coal underground mining employs slightly more than half of all coal mining industry workers, but experiences a higher share of occupational injuries, illnesses, and fatalities. The rate of fatal ...
The coal mine spoil dump was selected as a study area at Lajkura coal mine under Mahanadi Coalfields Ltd, situated in the north western part of Orissa State, India. The dump covers a leasehold area of 402 ha, out of which reclamation was carried out on an area of 10 ha.

Nov 12, 2015· Abstract. Few studies have been conducted on how the quantitative relationship between phosphorus (P) and iron (Fe) and aluminium (Al) compounds in the sediments of coal mine subsidence lakes influence sediment P release.
The water samples upstream and downstream from the discharge points from six mines were taken, and 110 parameters were tested. The results were assessed against a water quality index (WQI) which accounts for pH, turbidity, dissolved oxygen, biochemical oxygen demand, total dissolved solids, total phosphorus, nitrate nitrogen and E .coli.
MCM has been mining coal in Botswana since 1973. Coal Mine Changed its name from Morupule Colliery to Morupule Coal Mine (MCM) in 2011. MCM has a mining licence (4/76) which covers an area of approximately 425km2. The lease area contains an estimated total Coal Resource of approximately 2.9t billion.
SGS global teams of chemists and experts use a range of coal analytical calculations and indexes to arrive at the calorific values, total hydrogen, Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) of your coal sample.
phosphorus concentrations than those from the lower part. In all three coal-bearing formations, the amount data scatter within individual se.ams can be very pro- nounced. The range in average clean coal phosphorus concen- trations, 0.030 to 0.044 per cent, is smaller than the range.

Toxicology indices of metals present in industrial discharges were used as an additional tool to assess water quality, and the newly proposed environmental water quality index (EWQI) lead to better trend in the impact of coal and coal seam gas mining activities on surface water quality when compared to the upstream reference water samples.
The mining activities resulted in changed stream courses, channelized reaches, and mine tailing dumped along stream banks (McDonald, 1987; Kerwin, 2001). Headwater streams of the south fork of Coal Creek originate from a caved-in section of mine that seems to combine with an extensive mine drainage system (Skelly and Loy, 1985).
