Study on Extraction Technology of Undulated Steeply Pitching Coal Seam

摘要：

In order to study the extraction technology of undulated steeply pitching coal seam, the roadway lay - out and mining technology parameters are researched in detail at the basis of analysis the necessity of mining steeply pitching coal seam.The roadway lay — out and extraction technology parameters of undulated steeply pitching coal seam are put forward.The roadway lay - out is slope and the extraction technology parameters are bench blasting technology and ladder blasting technology by the occurrences traits of undulated steeply pitching coal seam and the production and practice in DaAnShan colliery.The optimization technology is ascertained to be two high benches by analysis the advantages and disadvantages of the two extraction technologies and the effectiveness of industrial scale experiment underground.So, the yield, recovery, work efficiency and safety are improved.
