摘　　要：为增大煤矿井下综采工作面过渡支架段后部空间,方便后部刮板输送机机头、机尾驱动部的安装、检修和支架的拉移,进一步发挥两柱式液压支架的特点,对两柱式液压支架进行结构改进,提出两柱式过渡液压支架结构,并成功应用于华亭煤业集团有限责任公司东峡煤矿急倾斜工作面。In order to increase the back space of the transition support section in the underground fully mechanized mining face of the coal mine, to facilitate the installation, inspection and repair of the head and tail driving part of the rear scraper conveyor and the pulling of the support, and to further exert the characteristics of the two-column hydraulic support, the structure of two-column hydraulic support was improved, and the structure of two-column transitional hydraulic support was put forward. It has been successfully applied to the steeply working face of Dongxia coal mine of Huating Coal Group Co., Ltd.
