Selection of an Appropriate Mechanized Mining Technical Process for Thin Coal Seam Mining

Table 1

Technical comparison of MMTPs.

MMTP	Advantages	Disadvantages
Conventional	Lower equipment investment; simple technology; high maturity	High labour intensity; poor man-machine environment
End-controlled	Liberating operators of shearer	Poor adaptability
Manual subdivision controlled	Lower equipment investment; reducing labour intensity	Adding several operators in site; lower safety degree
Automatic subdivision controlled	Liberating operators of shearer	Adding one operator in site; higher automated equipment investment; very poor adaptability
Presetting trajectory cutting	Liberating operators of shearer; high adaptability	High exploration input before mining; lower maturity
