1. 16Mn and Q460 account for the largest proportion, followed by the other Q550 and Q690, but they are rare and expensive. The main stress parts should be used well, and other parts should be used second.
2. According to the mining height, slope, mineral structure and environment of each coal mine, the type of hydraulic support used in a fully mechanized coal mining face is different
the common hydraulic supports are shield type, support shield type and top coal caving hydraulic support. But to subdivide, there are many other types, such as wire laying, thin coal seam, large dip angle, filling type, end hydraulic support, advanced hydraulic support and so on. However, the main structural forms of the roof of the supporting working face are no more than the three types of shield, support shield and top coal caving hydraulic support
if you want to know more about coal mine hydraulic support, pay attention to Henan hexinha
provide technical parameters, Atlas, drawings, processing, maintenance, price, weight and material of various types of coal mine hydraulic supports, and support supports, top coal caving supports, suspended supports and support supports from Zhengzhou Coal Machinery Co., Ltd., Linzhou Heavy Machinery Co., Ltd., Beijing Coal Machinery Co., Ltd., Shandong mining machinery Co., Ltd., Shandong Xinmei Coal Machinery Co., Ltd., Pingyang Heavy Instry Co., Ltd., Zhengzhou Siwei Co., Ltd.

Hydraulic support operation to master the eight operation essentials, to do: fast, enough, right, even, flat, tight, strict, clean. That is: "fast" - the operation should be fast“ Enough "-- the moving distance should be enough“ The operation is correct“ The moving speed should be even and stable“ "Three straights and two levelings" should be ensured in pushing and sliding frame“ Tight - timely support, closely following the shearer“ The support should be tightly connected with the roof and the gangue“ Clean up the floating coal and broken gangue in the frame before the frame. The specific operation is shown in the figure below:
