Geophysical Logging In Contrast Muli Coalfield Coal Rock Mining In Jiangcang

Jiangcang Muli Coal Mine locating in Tianjun County of Qinghai Province, with Juhugeng Coal Mine and Hushan Coal Mine, constitute the belt of Muli Coal Mine. It is one of the most important coal minerals in Qinghai. Jiangcang Muli Coal Mine is the largest mine in Muli Coal Mine, with the total resources/reserves/mine of 2.083 billion tons, most of which are coking coal. Jiangcang coal mine is in the central of Muli, extending from Northwest to west, and the area is about 55Km2. It is part of Jurassic continental clastic coal system construction, with a thickness of more than 596.01m, and it contains 20 coal-bearing layers (group), from top to bottom.Based on the regional geological Jiangcang mining, construction and mining geological features comprehensive research, through mine stratigraphic and geophysical characteristics of the analysis, the establishment of a coal and other rock formations in the area of qualitative, will be thick principles of interpretation and the main coal mining area of Jiangcang were compared, summed up the main coal seam geophysical characteristics of the area, and do a comparative evaluation of the reliability of the coal seam. Coal exploration proved able to provide the results of geophysical logging data accurate and reliable coal, rock, and other aspects of the structure, to make up for deficiencies in the construction process of drilling to verify the results of the hierarchical identification; and using geophysical characteristics of coal formations carried out an accurate comparison of the coal strata, coal seam thickness data distribution and the resulting high credibility. Coal in coal formations geophysical logging has unique advantages comparing aspects, methods and reliable, easy to operate, thereby increasing the efficiency of exploration and exploration project quality.
