Research on the thick very loose coal bed driven along the bottom of roadway supporting
This paper using 8203 machines tunnel and wind tunnel as the research object comprehensively introduces a thick very loose coal bed driven along the bottom of roadway support technology in Anhui some coal mine.It is not only describes the specific supporting programs,but also introduces support basis in detail,field trials,monitoring reports about proving the effect of supporting.It also creates a huge effective technological change.The background of this paper is a successful scientific collaboration between coal enterprises and universities.Its significant achievements in scientific researches are not only reflecting in the huge economic benefits,but also having high academic value.It revealed forced supporting weak pressure,weak supporting forced pressure theory not only has the great significance to improve the supporting theory of the existing mine roadway,but also has important reference value to change the supporting difficulties of the thick very loose coal bed and the status of repeatedly repair in our country.
