Recently, with the start of the coal cutter in the No. 1203 North No. 2 working face of the Xima Coal Mine of Shenyang Coal Mine, it was marked that the installation work of the working face passed the acceptance and entered the initial mining commissioning phase.

The recoverable reserves of 1203 coal mining face is 25,3190.3 tons, which can be mined for about 5 months. It is the main project of the coal mining team in the second half of the year. The whole face of the working face is in an inclined structure. The roadway is a rectangular section with a sectional area of ​​11.44m2. In the process of mining, it mainly adopts the approach of long-wall retreat-type one-time mining and full-height mining, and uses bolts and anchor cables to support the joints, and erects 12# miner steel trapezoidal sheds at the crushing place of the roof. In response to the problem of water damage during the mining process, the mine has formulated methods such as laying water tanks, emergency drainage pipes, and sedimentation tanks on the working surface to ensure safe production during mining.

The successful test production of the 1203 working face laid the foundation for the realization of the mine's safe production goal in the second half of the year.
