The technical personnel in underground coal mine village 5207, 5208 face big divide by cross fault, which is difficult to influence the problem of production system arrangement,. He was the first one to propose and implement the "Borrow adjacent coalfaces stopping production system technology," With Shandong University of Science and Technology cooperation completed the complex structure area adjacent coalfaces production systems to improve the “Use resource for recovery technology "research project. Technical personnel’s scientific, reasonable and system arrangement to each piece of period of mining sequence, from the system and technology to ensure the 5207 and  the 5208 mining, improve the security and efficiency of the fracture structure extremely complex area of the coal resources recovery, for mine created huge economic benefits.
      On December 26, 2010, this research project smoothly through the department of Shandong province technical appraisal of experts. Appraisal committee agreed that the results of the study have reached the international advanced level, and have larger application value in the coal mine safety in production process.
