在较高巷段即巷道进尺55~155 m施工帮部锚索减缓帮部变形速度;通过在巷道底板施工横向水沟、左帮根部铺设流水槽、施工沉淀池及铺设排水管等,最大限度地把底板水引向流水槽,减少巷道底板冲刷程度及糊煤严重性;另外施工过程中采取在综掘机履带下方垫道木等措施使综掘机平稳向前推进,及利用铺设的水泥台阶来减轻行人压力。通过以上几种措施的实施,顺利地通过了较高巷段。
In the upper section of the laneway, 55-155 m, the anchor of the construction gangue will slow down the deformation speed of the gangway. By means of horizontal ditches in the laneway floor, laying of flow trough in the root of left lane, construction of sedimentation tank and laying drainage pipes, etc., the maximum limit To guide the floor water flow tank to reduce roadway floor erosion and paste the seriousness of the other in the construction process to take the road under the track excavator wood and other measures so that the smooth progress of the roadheader and the use of laid concrete steps To reduce pedestrian pressure. Through the implementation of the above measures, successfully passed the higher lane.
