我矿是已开采46年的老矿,随着矿井开采的不断深入,3#煤层资源日趋枯竭,为尽可能延长矿井开采年限,9#煤层与3#煤层资源合理配采就显得尤为迫切。从1995年我矿进入9#煤层回采以来,至今已近10年,共回采了11个综采工作面,2001年在93304工作面首次使用某煤机厂生产的ZZ4000-10／21型支撑掩护式液压支架,随后,在92304工作面、93305工作面和刚刚进入试生产的91307工作面使用。现结合生产中的实际情况,对ZZ4000-10／21型液压支架的使用情况进行总结,以便为今后9#煤综采工作面液压支架的选型提供科学、合理的依据。
As the old mine that has been mined for 46 years, with the deepening of mine exploitation, the resources of No.3 seam are depleted. In order to prolong the mining life of the mine as much as possible, it is particularly urgent that the mining of 9 # and 3 # coal seam resources should be rationally allocated. Since 1995, I entered the 9 # coal seam mining has been nearly 10 years, a total of 11 fully mechanized mining face, in 2001 93304 face the first time using a coal plant ZZ4000-10 / 21-type support cover Hydraulic support, followed by 92304 working face, 93305 working face and 91307 working face just entering the trial production. Now combined with the actual production situation, the use of ZZ4000-10 / 21 type hydraulic support to summarize in order to provide scientific and reasonable basis for the future 9 # coal mining face hydraulic support selection.
