Taking the 12162 working face of a certain coal mine as an example,a combined support scheme of bolt-net-cable in the roadway was introduced.Through relevant calculations,the parameters of bolts and cables in the bolt-net-cable support system were determined,and based on this,multiple different support schemes were designed.Then,finite element analysis was used to simulate and analyze each scheme,in order to select the best bolt-net-cable combined support scheme.The application of bolt-net-cable combined support scheme can significantly improve the stability of the roadway working face,confirming that the scheme has certain practical value.
