在综采工作面回采过程中,两顺超前支护的顶板管理十分重要,它是保证回采工作顺利进行的最重要因素之一。而复合型顶板具有易离层、易折断、稳定性差、支护难度大的特点,在顶板安全管理上,是一个长期困扰综采两顺巷道维修工作的难题。大兴煤矿通过采取有力措施,及时、合理改变支护方式,达到了对顶板的有效控制,保证了安全生产和回采工作的顺利进行。
In the process of fully mechanized coal mining face, roof management of Liangshun advanced support is very important, which is one of the most important factors to ensure the smooth progress of the mining work. The composite roof with easy to leave the layer, easy to break, poor stability, difficult to support the characteristics of a large, in the roof safety management, is a long troubled two fully mechanized mining roadway maintenance work problems. Through adopting effective measures, Daxing Coal Mine timely and rationally changed its support methods to achieve effective control of the roof and ensured the smooth progress of safety production and recovery work.
