Top coal caving mining technique in thick coal seam beneath the earth dam
Based on the geological and mining conditions, the top coal caving harmonic mining technique in thick coal seam beneath the earth dam was put forward and studied. The 5 factors such as the panel mining direction, panel size, panel location, panel mining sequence and panel advance velocity were taken...

Earth dam Coal caving mining technique Based on the geological and mining conditions, the top coal caving harmonic mining technique in thick coal seam beneath the earth dam was put forward and studied. The 5 factors such as the panel mining direction, panel size, panel location, panel mining sequence and panel advance velocity were taken into account in this technique. By taking some protective measures on the dam, the top coal caving mining technique in thick coal seam beneath the earth dam was carried out successfully. The study demonstrates that harmonic mining in thick coal seam is feasible under the dam. The safety of the earth dam after mining was ensured and the coal resources recovery ratio was improved. https://www.sciencedirect.com/science/article/pii/S2095268616301884 2020-02-18T02:31:40Z 2020-02-18T02:31:40Z 2017 20181009100613.0 130605s2017 BB International Journal of Mining Science and TechnologyVol.27, Issue 1 (Jan.2017), pp. 165-170 http://tailieuso.tlu.edu.vn/handle/DHTL/5076 eng |
