Definitions
- the present invention relates to a process for maximization and optimization of Coal Energy, more particularly the present invention relates to a process which optimizes the coal energy utilization.
- Coal is one of the most rich and abundantly available energy resources in the world.
- the need for the conservation and optimization of all the carbon generating energy resources are attracting the center stages at all international forums.
- the need for the optimum utilization of the available energy with minimal green house gas production is of utmost necessity.
- Object of the present invention aims at developing a process for maximization and optimization of coal energy.
- Object of the present invention is to develop a process, wherein the loss of coal energy during the course of the coal winning can be saved.
- Another objective of the main invention is to maximize the production of coal generation and use the same for generation of power.
- Yet another objective of the present invention is to maximize the power generation from coal which can result into reduction of cost for power generation.
- FIG 1 shows the Panel preparation
- Figure 2 shows Plan of Mine.
- FIG. 3 shows Panels divided into slices
- Figure 4 shows Developed Mine Plan
- Figure 5 shows Borehole pattern
- Figure 8 shows 3 D view showing ascending extraction of slices
- the working will be kept in isolated panel from other workings by airtight isolation.
- the panel preparation will facilitate sub- surface dewatering and uninterrupted working of panel due to water problem especially in case where aquifers are present.
- Subpanel is divided into number of slices for extraction of coal energy at a time
- the seam is approached by set of boreholes for coal energy extraction and boreholes for filling of voids.
- the number of boreholes, diameter of boreholes and positioning of boreholes depends upon certain determining factors such as
- the slice will be extracted by different compartments to facilitate complete extraction of coal energy within the permitted area of exposure. As shown in fig no 6 the sequences of extraction of slice in compartment.
- the extraction height is kept within limit as less as possible by continuous partial filling of voids (as low as 1.5 meters or less). It will facilitate more area of exposure as height of extraction has direct effect on roof fall
- the voids should be complete filled even inlet and exhaust holes can be used for the purpose.
- the fig no 5 will show the extraction of slices in compartment.
- the fig will give the sequence of extraction of adjoining slices and slices in upper seam.
- Methane (CH4) formed as emission or distillation of coal burnt below heat extraction pump by installing activated platinum wire gauze and heat generated will be used for stem generation. Different technologies and experiences used in extraction of coal energy
- a coal mine is initially divided into number of panels preferably of 200/200 meters and the said panels are divided further in to sub panels of 45/200 meters.
- the said panels are thereafter converted into the dewatered compartments.
- the said compartments are thereafter provided with the boreholes of diameter of 24". The stowing is done by bore of small 8" diameter.
- fire is enlightened in the coal seam by using the advance torch technology.
- the controlled and predetermined air is infused in sub panel during the combustion of coal to keep the fire in control.
- the extraction of heat is also done in controlled manner in order to maintain the combustion in the advanced stage, thereby reducing the emission of green house gases like Carbon Monoxide or Hydrogen.
- the same is further achieved by filing the voids formed by the combustion of coal.
- the panels are selected in such a manner that the roof of the panels shall not fall at any point of time during the process. Thereafter the heat generated from the combustion can be utilized for generation of power by using the state of art technology.
- the process is capable to bring down the cost of electricity 40-50 paisa/unit.
- T.P.S. Thermal Power Station
- the process is free from degradation of land and has comparatively less environmental impact with potential of lowering the overall capital and operation cost.
