大雁煤业公司第二煤矿自1994年开始采用综采放顶煤采煤法生产以来,累计回采了6个综放工作面。在对6个综放工作面进行回采过程中,通过不断地对综放工艺、技术、采场控制、设备管理以及现场管理等方面的探索和总结,积累了丰富的综放工作经验,取得了一定的成绩。以前由于缺乏技术支持和有效的管理方法,在对综放面回采过程中,最高日产量仅为2750t,月产7.5万t。而今年在对305阶段30#2综放工作面进行回采过程中,由于采取了科学合理的综放工艺技术,有效的采场控制手段和管理方法,创造了日产10083t,以及年单产236万t的煤业公司成立以来的最高水平。现将对综放工作面回采的生产实践活动做如下总结:
Since the second coal mine of Dayan Coal Company started to adopt fully mechanized top coal caving method since 1994, a total of 6 fully mechanized coal caving face has been recovered. During the process of six fully mechanized coal caving face, we have accumulated rich experience in the work of fully mechanized top coal caving through continuous exploration and summary of technology, technology, stope control, equipment management and on-site management of fully mechanized top caving. Certain achievements. In the past, due to lack of technical support and effective management methods, the maximum daily output was only 2750t and the monthly output was 75,000 t during the recovery of fully mechanized coal caving face. This year, during the process of 305 # 30 # 2 fully mechanized caving mining face, due to the adoption of scientific and reasonable caving technology, effective control measures and management methods of stope, it created a daily output of 10083t and an annual yield of 2.36 million t The highest level since the coal company was founded. Now we will summarize the production practices of the fully mechanized caving face mining as follows:
