Paper Title:
Study on Mining Techniques for Improving Lump Coal Rate of Anthracite
  Abstract

Based on the decisive impact of mining techniques on lump coal formation, according to the specific mining conditions of 2206# coalface in Xinqiao Mine, the turning direction of rollers in coal winning machine had been changed, the cutting coal ways of coal winning machine had been transformed, the supporting strength of hydraulic supports had been reduced and the presplit short-delay blasting had been implemented for improving the lump coal rate of anthracite. The application results show that those mining techniques could greatly improve the quantity and rate of lump coal and make better technical and economic benefits.
