Research Of Informational Construction Management In Freezing Method Sinking Of Guobei Coal Mine

Coal is the main energy in China and an important industrial raw material.Our country has put forward higher requirements about aspects of coal production in efficiency and safety with the development of the national economy.Coal mine shaft construction is to serve the entire cycle of coal mine production and the drilling technology and quality are important parts related to coal mine production safety.Currently freezing shaft sinking,which is an effective way to drill coal mines in unconsolidated aquifers, has a wide range of applications.But how to ensure the safety,high quality and efficient construction of the deep freezing sinking is still an important problem.In the actual construction, the method,which applys the information technology in the field of construction management,bases on field data,combines with the actual construction process and uses feedbacks to guide the next step after the computer analysis,can play a positive role in the correct guidance of the construction safety.This thesis builds a project informational management system and achieve a number of aspects such as feedbacking the security of the freeze walls,the wall structure safety and monitoring results to the decision-making of the projects,the project design,and the project construction accurately and high-efficiently on the basis of a large number of engineering practice and in-depth research for deep-thick topsoil freezing sinking mine drilling construction process at GuoBei Coal Mine.At the same time,we receive a large number of monitoring and controling data for regulating the safety of the well-shaft construction via the monitoring of the informational construction.We also adjust the construction of freezing shaft sinking dynamically combined with test data.And all these above finally play an positive and important role in avoiding hidden safety problems of shaft construction and mine construction.
