No. 7 seam average thickness of 10m，No. 9 seam average thickness of 3m. Mine the normal inflow of 140m3 / h , the maximum inflow of 160m3 / h ; mine the relative gas emission in 6m3 / t , is a low - gas coal mine . Zhang small building Ida Industrial reserves for 303.42Mt , recoverable the reserves 220.73Mt , mine design production capacity of 2.4Mt / a , mine service life of 65.7a . According to Ida geological conditions , the design uses a dual vertical shaft and the dark inclined to extend the two-level open up the way , the first level of elevation - 600m , down the mountain mining under the mining - 900m , the second level of elevation of - 1130m - 1100m elevation above using the mountain mining, the following bands mining this elevation . Ida total is divided into six mining area , the two bands , track roadway and roadway of the belt conveyor are rock roadway layout in the No. 9 coal seam floor strata . Take into account the mine for the low gas mine , mine ventilation mode with a central parallel ventilation . Using the mining area to prepare for the North mining area , divided into a total of five face , and coal , ventilation, material transport , to discharge refuse , power supply system design. In 7101 working face mining technology design.The work face coal seam average thickness of 10.0m, the average angle 25 °, immediate roof for arenaceous shale, sandstone roof.Working face with fully mechanized top coal caving mining.Double drum shearer cutting coal, and a cutting knife two.The "three eight system" working system, cutting depth of 0.8m, every four cycle, cyclic footage of 3.2m, 96m month advance. Lane using belt conveyor coal, auxiliary transport using battery locomotive traction fixed-box type mine car.Main shaft using two pairs of 12t long skip coal, auxiliary shaft adopts a 1.5T car four car transport material widened double cage and lifting personnel. Special section entitled "Zhang Xiaolou" by Zhang Xiaolou microseism analysis, 95206 working face for the project as the example, has carried on the detailed micro-seismic monitoring and data collecting and processing, gives Zhang microseismic activity law of mine production practice, and the prevention and control of mine rockburst has significant guiding significance. Translation part titled "WAVEFORM EFFECT ON PRE-AND POST-FATIGUE PROPERTIES OF SANDSTONE", mainly describes the different waveform on fatigue characteristics of sandstone.
