Application of Low Specific Pressure Type Anchoring Equipment in Huangling No.2 Coal Mine
ZHANG Dongbao
Abstract：In order to solve the problems of a large number of workers,high work intensity,and poor working environment in the tunnel excavation process of Huangling Mining Company's mine,a low pressure type excavation and anchoring integrated machine that can adapt to the special coal mine conditions in Huangling mining area was developed by using the method of studying the process,equipment,and application as a closed-loop system.Its overall structure,technical characteristics,and industrial test results in No.2 coal mine were introduced.Experiments have shown that the low specific pressure type integrated mining and anchoring machine has achieved one-time excavation and shaping of rectangular sections under special tunnel conditions,parallel operation of mining support and anchoring,improved excavation efficiency and production efficiency,and provided important technological support for the transformation of production methods in the coal industry.This has opened up a new path for the development and research of anchoring equipment under other complex geological conditions in China.
