An underground gangue transport, storage, and filling system is directly set up underground; a large volume of coal gangue mined from a coal-and-rock mine face is transported to an underground sorting and washing chamber, where coal and rock are separated highly effectively; the separated gangue is crushed, then filled into a protected-layer goaf; the gangue is not lifted out of the mine, while the protected layer is filled and mined in a green manner, effectively preventing the settling of the land W O 2017/219624 A7/219624Al|||||||||||||||||||||||||||||||||||||||||||||||||||| (74) {- 1j, 85 )si( j jk) (NANJING RUI HONG PATENT AND TRADEMARK OFFICE LLP); S l t A7 n n i tr M A fltt1l3042, Jiangsu 210000 (CN)o (81) tq-%Tpd( t 3~-tV 4#P4f LPM (f-,T ) : AE, AG, AL, AM, AO, AT, AU, AZ, BA, BB, BG, BH, BN, BR, BW, BY, BZ, CA, CH, CL, CN, CO, CR, CU, CZ, DE, DJ, DK, DM, DO, DZ, EC, EE, EG, ES, FI, GB, GD, GE, GH, GM, GT, HN, HR, HU, ID, IL, IN, IR, IS, JP, KE, KG, KH, KN, KP, KR, KW, KZ, LA, LC, LK, LR, LS, LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZWo (84) fl-%Tpd( trT, h A, 3 4-#iPN~Ttf4g f {fft) : ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), K[ R (AM, AZ, BY, KG, KZ, RU, TJ, TM), K#tJ (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG), * R$1)|9M I @J4. 17 PAB] - 5 U) )[I (J4. 17 (iv)) - dF;- * TR V)$$ ( M 2 1 * (3))o surface caused by the joint mining of multiple layers of coal; the separated medium coal is transported via a main transport system to a surface gangue power plant and used for power generation; the power plant produces a benefit and pressure on the coal quality of the mine is reduced, decreasing the average ash content of the commercial coal and raising its sale price. Coal and gangue are separated very effectively and the coal and rock are utilized in a highly effective manner, the economic benefit and social benefit both are significant, and the invention is valuable for widespread promotion.
