Efficient and fast tunneling of underground roadway is an important means to improve the production efficiency of coal mines. With the continuous increase in the demand for coal in the economic development, it is a realistic problem that the coal mine enterprises need to solve to improve the driving speed, efficiency and quality of the mine tunnel. In this paper, the construction for the roadway heading face of Huojitu in the Daliuta mine is studied. 1 the ground relative position and geological condition of the laneway of the live chicken and rabbit well in the Daliuta coal mine are analyzed. The relative position of the ground and the mining conditions in the adjacent area, the characteristics of the coal seam and the geological structure, the hydrogeology, the existing problems and the matters of attention are found. 2 the roadway layout and support design of the live chicken and rabbit well in the Daliuta coal mine are determined, including the position of the working face and the use of the roadway, the amount of engineering and the time of opening and completion are calculated, the layout of the roadway is determined, the design of the support, the support technology and the technical requirements are determined, and the of the observation of the mine pressure is determined. 3 the construction and process are determined, including the determination of the construction the technical features of the main equipment in the working face, the order of the roadway driving and the driving process coal falling process, coal loading process and coal operation process. 4 the 12 major production system layout s for the working face have 西安建筑科技大学硕士学位论文 been determined. 5 the quality of the working face, the management of coal quality and the main economic and technical inds are determined, including the coal quality index and the guarantee measures of coal quality. The of setting up the labor organization is determined and the main technical economy of the working face is calculated. Indicators. The construction of driving face in the tunnel of the live chicken and rabbit well in the Daliuta coal mine will combine “digging“ with “anchor“ and “continuous transportation of coal flow“, and realize the parallel operation of excavating and anchoring to the maximum extent, and using a equipment to complete the driving and supporting work at the same time. It has a roadway, the speed of construction is fast, the roof support is well supported, and the roadway is used. With the advantages of road specifications and standards, at the same time supporting the corresponding transportation system, it meets the requirements of roadway safety, rapid quality and high quality.
