ABSTRACT
The designation is based on actual situation of Lu Jiatou pit of the Kailuan Mining Group in Hu beifor the the preliminary design. There are 41 square kilometres of well field area and 2,400,000 tons of coal annually to be designed, whose coal bed gives deeper layer and inclination is not lager, the average thick is about 3.83m, geological structure is simple, the volume of gas poures out relatively larger, coal bed has natural fireing tendency, and the colliery water is middle in cacity .
This design adopts the erected sheft mining method and belt-ready way. In addition to using skewed towards long walland methods, integrating mechanized stoping techniques, That is the main way to open up the pit, preparing forms, coal mining methods for preliminary design. As well as transport, ventilation, drainage systems and other production equipment models calculated to pit various production systems described in the production process, Besides, I want to describe various production systems of the pit and the interlinkages between the production relations and the constraints on the statement. In the design process, both shaft whole realize mechanization,adopt advanced techniques and use for reference afterwards realize high yield highly active modernization shaft 'experience,realize one mine not both high yield highly active shaft thereby run up to favorable economic benefit and social benefit.
