Why HOT Know How? 为什么选择HOT提供薄煤层成套? -How to develop Low-Seam Underground Coal Mining
Coal mines in southwest China are difficult mining which mostly belong to the low, steeply
pitching and faults reserved coal seam; experts of HOT are the people who have many
years’ experience in low coal seam mechanised mining and production management
engineers from Chongqing Coal Group, Sichuan Coal Group and Yunnan Coal Chem
Company, etc.
Coal mining machine experts: Xiang-Dong Liu, he is awarded special government
allowances by State Department, one of the first batches of specialized technical
talented person of the original ministry of coal industry. He is the 2013 national coal
machinery industry outstanding chief engineer and he awarded second prize of
Technology Progress of the original ministry of coal industry. Mr. Liu is the founder of
coal shearer OEM factory of HOT Mining, The independent director of HOT, the
Chongqing Coal Group consulting expert group leader. He has more than 30 years’s
experience in research and development of low seam coal mining machine and fully-
mechanized longwall complete implementation.
Thin coal seam fully-mechanized management expert: Prior to join HOT Mining, Mr.
Da-hui Yang, he is deputy general manager of Yunnan Coal Chem Company and
external expert of HOT. He has nearly 40 years’ experience of coal mine production
management. He guided Housuo Coal Mine and other similar projects to complete
successful implementation of low coal seam fully mechanized.
Fully-mechanized complete implementation and chief mining engineer: Fei Mao.

Technology - Cantilever Roof Support
It takes about 1~2 minutes to finish the whole 3 steps, which is equaled to
the fully mechanized longwall mining.
Features - Cantilever Roof Support
1. Large Supporting Area
Because the top beam section is integral box-type structure with dimension of 0.96m width
and 2.6m length. The supporting area is more than 96%, which is same as fully
mechanized longwall mining support, so the support can be used in broken roof working
face. And there will be no roof leakage of high-grade working face and cantilever roof
support working face.
2. Fast Advancing Support Speed
The advancing velocity of working face is faster due to the simple moving method. And it
can absolutely meet the speed requirement of mechanized mining working face.
It takes about 1~2 minutes to finish the whole 3 moving steps, which is equaled to the fully
mechanized longwall mining.
3. Good Stability
Because full working face is linked as a whole through the beam system, it has good
stability, working face can make sure the support will not fall. If there is head space above
certain support or it is not supported well, overall moving beam and top beam suspension
system make it will not fall, so the working face completely avoid the phenomenon of
support’ s skew and fall, security is greatly increased.
