Scope 
 MJ30 MJ22 cutter cutter in the ambient air methane, coal dust, hydrogen sulfide, carbon dioxide content of no more than "Coal Mine Safety Regulations" under the security content of mine to use. Coal mine for most small and medium mining height 0.45 m above the coal seams dipping very thin open cut coal face trough purposes. 
 Suitable for cutting coal hardness f ≤ 4 ° face. 
 Suitable angle along the bottom wall of coal a <25 ° face. 
 Features: 
 The small size, light weight, reasonable structure, convenient maintenance. 
 The machine has a certain part of explosion-proof electrical performance, electrical cooling of water, cooling water jet cutter, dust-proof effect. 
 The more manual machine can greatly increase the lump coal rate, save mining time for enterprises to significantly improve economic efficiency. Thin seam mining complex is an alternative artificial undercutting coal drop the best equipment.
