3. 1
Due to the lack of more useful information such as geological structure, gas,
hydrogeololgy, roof and floor conditions, power supply, transportation and ventilation
system, we made the proposal below just according to the available information.
1. About the Supporting Method and Cross-section of the Roadway
(ventilation roadway and mechanical roadway)
1.1 Trapezoid roadway
Ventilation roadway: upper net width is 2.4-2.6m, lower net width is 3.4-3.5m, net
height is 2.1-2.2m.
Mechanical roadway: upper net width is 2.9-3.1m, lower net width is 4-4.1m, net
height is 2.1-2.2m.
1.2 Semi-circular arched roadway
Ventilation roadway: net height is 3.1m, net width is 3-3.2m.
Mechanical roadway: net height is 3.1m, net width is 4m.(Comprehensive
transportation roadway)
1.3 Abnormity roadway
Ventilation roadway: lying side net height is 2m, net width is 3.2-3.5m, and is
suggested to be supported by wire meshes beam.
Mechanical roadway: lying side net height is 2-2.2m, net width is 4-4.2m.
The three roadways above need to be controlled according to the middle waist line
when advancing.
1.4 The layout of open-off cut
The hydraulic support of the trend width could add 1m additional, the supporting
system is suggested to use wire meshes beam.

4. 2
2 Estimation of the Annual Output and Monthly Output
Advancing output per 1m: 160*1.1*1.4*1=246.4 ton.
(longwall working face length*mining height*density*advancing rate)
Daily output could be 591-887 ton based on 4-6 circulation.
Monthly output could be 14775-22175ton if works 25 days.
The annual output could reach 147750-221750ton if works 10 months (deducting the
dismantlement and installation of the working face).
If there’s no coal and gas outburst, no heavy tectonic fault, the maximum annual
output could be 350000-400000ton.
Generally speaking, the annual output is 250000-300000ton, because in the ultra low
coal seam the coal shearer couldn’t operate too fast, the machine height will influence
the coal production, workers’ physical exertion is too heavy and etc. The lower end of
the working surface needs to be made an advance gap. The monthly advancing rate is
60-100m, and annual advancing rate is 700-1000m.
