Research And Application Of Coal Seam Strip Mining Method With The Huge Thick Soil Layer Under Buildings

Based on the strip mining research , for resolving the mining problem effectively under building currently, and Combining the condition as geologic, mining and mining method with QIAN JIA YING coal company branch, this paper research the strip mining cover with the huge thick soil layer, and design the relevant project. Combining the actual condition of the spot to take to mine width and reserve width, coal pillar stability, strength, the earth's surface ambulation to transform physically etc. according to the domestic and international related technique theories, and then make a detailed of analysis and verification. Also make the spot experiment, the ground transform monitor, the mineral pressure observation etc.,at the basis of earnest researching of the project result and observation data, educe the mine damage valuation, the earth's surface ambulation transform regulation and the design parameter and so all. And to be referrence for strip mining method of related design and theories in other place in the similar condition, for exaltation and development the" SAN XIA " mining technology provide the beneficial instruction and help.
