7、式通风ABSTRACTThis design includes three parts: the general design, the monographic study and the translation.The general design is about a 1.5Mt/a new underground mine design of Xutuan Coal Mine. Xutuan Coal Mine lies in the southwest of Suzhou City, Anhui province. The transportation in the mining ar
8、ea is very convenient. Its about 6.36.8km on the strike and 2.143.82km on the dip, with the 22.75km2 total area. There are 8 minable coal seam. The main aquifer coal seam is 72 coal seam with an average thickness of 3.0m .Both the dip of coal seam is 716. The proved reserves of this coal mine are 30
9、2.8. Mt and the minable reserves are 206.45Mt, with a mine life of 98.3a. The normal mine inflow is 550m3/h and the maximum mine inflow is 660m3/h. The mine relative gas emission quantity is 12.0m3/t, and the absolute gas emission quantity is 37.879m3/min. Thus, it is a high gas mine. The coal seam
10、range from tend to spontaneous combustion to have no tendency of spontaneous combustion, and the coal dust has explosion hazard.Based on the geological conditions of the mine, I bring forward four available project in technology. The first is vertical shaft development with single mining level and c
11、entralized juxtapose ventilation; the second is vertical shaft development with single mining level and two wings of diagonal ventilation; the third is vertical shaft development with two mining levels, the deep extension of blind slope; and the last is vertical shaft development with two mining lev
12、els, the deep extension of blind slope and blind shaft. The first project is the best comparing with other three projects in technology and economy. The mining level is -690m, and the mine field is divided into five strip districts and two mining district, with centralized juxtapose ventilation.Desi
13、gned first mining district makes use of the method of the mining district preparation. The design length of working face is 210m, which uses fully mechanized mining the full -height. The working days in one year are 330. Everyday it takes 16 hours in lifting the coal. The operation mode in the mine
14、is “three-eight” with two teams mining and the other overhauling. Every mining team makes three working cycle, and the overhauling team makes one working cycle. So everyday there are 7 working cycles. The advance of a working cycle is 0.8m, and the quantity of 4127.71 ton coal is maked everyday.Main
15、 roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. The main shaft uses two double 16t skips to lift coal and the auxiliary shaft uses a twins wide 1.5t four-car double-deck cage to lift material and personnel transportation.The monographic study e
16、ntitled “ Research on bolt and steel meshsupport technology for mine roadway driving along goaf in Xutuan coal mines”. The study mainly analyse the instability failure reasons of fully-mechanized caving roadway with the application of gob-side entry driving. Then give a theoretical analysis the widt
17、h of the protective pillar and how to make a reasonable choice of lane in the position. Finally, the corresponding control measures and control mechanism on surrounding rock, which in the core of high resistance and yielding bolt, are raised in this study.The theoretical analysis of the stability an
18、d failure reason of the surrounding rock of roadway, through theoretical calculation and numerical simulation identified reasonable width of coal pillar, and combined with the surrounding rock deformation characteristics and supporting principle put forward high strength bolt mesh anchor support tec
19、hnology, through the field tests, the effect is good in Xutuan coal mines 72403 working face return airflow roadway along goaf as engineering background.The translated academic paper is about customer value of Japanese coffee service by analyzing the huge tweet data set.Its title is “ A Method for O
