Sun Tuan mine located in anhui province huaibei city. The coal mine, the south territory renlou coal mine with borders, north and northeast willow from SuZhouShi compartmentalized adjoins, about 23km. There can be many highway compartmentalized SuZhouShi and MengChengXian huaibei city, to. East, west and the field respectively jinghu railway, south Sui railway and mining area was Tuan) ~ railway green (model (ridge) feeder after. The traffic is very convenient.Whole field north-south 9.57 km long, 3 ~ 5km tilt width something km2, with a total area of about it. The Lord CaiMeiCeng layer, namely 10 ° obliquity 17, average coal seam, thick about 2.73 m. Field 308.24 Mt for industrial reserves, recoverable reserves 234.41 Mt, the mine for a service life 93.01. Field geological condition is simple. The topsoil average thickness 50 m; Mine normal section for 383 m3 / h, maximum section for 520 m3 / h; Coal seam hardness coefficient f = 2.3; For mine absolute gas flow-volume 1.84 m3 / min, belong to low gas mine; Coal spontaneous combustion tendency, flaming a period of 3 ~ 6 months, coal-dust explosion hazard with.According to the geological conditions, compartmentalized proposes four technically feasible development plan. Plan a single level down the shaft: mining, level DaHang 550m, coal seam in -; Scheme ii: single level down the shaft mining, in - 550 level, rock DaHang; Plan 3: two levels inclined shaft mining extending to dark - 900 m level; Plan 4: two level mining, cutting extends to the vertical Wells - 900 m level. Through the technical and economic comparison, ultimately determine the optimal scheme for option 3. Will the Lord CaiMeiCeng divided into two levels, a level elevation - 550 m, two level elevation - 900 m, for large fault will be compartmentalized into compartmentalized is divided into two parts, compartmentalized south south service scope for a level for two level, northern no.1 service scope.Design the first panel adopts mining ways to prepare, face, the time length 2.5 m in coal mining method, all the high across fell method processing goaf. Mine using “38“ exercise, two class production, bus overhaul. Every four cycle shift, rijin eight circulation, circulation 5454.54 0.8 m, daily output footage t.DaHang introduced.in by belt conveyor by 1.5 t, auxiliary coveyance fixed box harvesters. Equipped with a set of main shaft 12 t double skip and a set of 12 t single skip belt balance hammer carry coal, a 3 t harvesters pregrouting equipment with double bikes for balance hammer cage auxiliary coveyance task. Mine using two-wing diagonal type ventilation. Mine ventilation easy period should always be airflow 1027-1032 m3 / min, mine ventilation total resistance 1588 Pa, wind resistance 0.33 N · s2 / m8, accumulate hole 2.07] m2, such as mine ventilation easy. Mine mine ventilation difficult times total volume air 1027-1032 m3 / min, total resistance of mine ventilation 2200Pa, wind resistance 0.46 N · s2 / m8, accumulate hole 1.75 m2, such as mine ventilation medium difficulty. Design the tons of coal mine cost 110 yuan/t.The projects section discusses the topic is sihe coal mine gas treatment and utilization technology. Using ground extraction and comprehensive utilizationTranslation part is an article about the control of mining coal-dust, the original English essay titled: On the wall of dust control to
