兴隆庄煤矿自投产以来,有四个综采工作面生产,一个是英国成套设备,三个是日本成套设备。四个工作面均开采三层煤(平均厚度8.6m),每一分层(采高2.5～3m)采用走向长壁倾斜分层采煤法,地质构造比较简单,为二类二级顶板。工作面超前压力一般在15m左右。自投产以来,四个综采队都达到等级队水平。其中综采一队83年元月份创造出101213t的全省最高纪录。在顶板管理方面,我们重点抓了上下出口的维护,保证了工作面端头畅通无阻,实现了安全生产。我们搞好上下出口的做法是:
Xinglongzhuang coal mine has been put into operation since the four fully mechanized face production, one is the British complete sets of equipment, three complete sets of equipment in Japan. Three coal layers (average thickness: 8.6m) are drilled on each of the four working faces. Longwall inclined stratified mining method is adopted for each stratification (mining height 2.5 ~ 3m). The geological structure is relatively simple and is a second-class two-level roofing. Face pressure ahead of the general about 15m. Since the put into operation, all four fully mechanized mining teams have reached the level of team level. One of the fully mechanized mining team in 83 years in January to create the highest in the province’s record of 101213t. In the roof management, we focused on the maintenance of the upper and lower exports to ensure that the face ends smooth and achieve safety in production. We do a good job up and down the export of the practice is:
