迈步支撑组合超前支护支架在鹤煤六矿综放面两巷的应用

Application of advance supporting support of striding and scraping in two roadways of full-mechanized caving face of Hebi No. 6 Mine

综放面两巷超前支护是回采的关键环节,同时也是一个管理难点。针对鹤煤六矿综放面两巷压力大,工作面前方10 m范围内压力显现明显,传统单体双抬棚支护支承强度难以满足两巷支护要求。根据该矿实际,研制了综放面两巷迈步支撑组合超前支护支架,在2146综放面两巷应用,取得了良好的实际效果。

Advancing support is not only a key link, but also a management difficulty in the process of mining. It was difficult to meet the support requirements of two lanes which tradition hydraulic props support in front of the work 10 re,due to high pressure of full-mecha- nized caving mining face of Hebi No. 6 Mine. According to the practical situation, it has been developed the advance timbering supporting set of the striding and scraping. Through the application in the 2146 fully-mechanized caving mining face, good results have been a-chieved.
