1.石嘴山矿务局生产的煤炭主要供铁路机车和电厂作动力煤用,生产部门按动力用煤对待,造成三层厚度在0.7～1.0米范围内波动的煤层不可采。我个人意见是从资源勘探始就按炼焦煤进行资源评价和储量计算,这样可最大限度地利用煤炭资源储量,延长矿井服务年限。2.由于这几年物探技术发展较快,特别是地震法,各项参数输入计算机处理很快,准确性高。因此,建议改变宁夏地区单纯靠钻探的勘探方法,采用物探方法搞综合勘探。这样能有效地减少钻探工程量,缩短勘探周期,节约投资。3.《煤炭资源勘探规范》规定构造中等,第一水平高级储量比例,大型矿井为60%、中型
1. The coal produced by Shizuishan Mining Bureau is mainly used for power coal for railway locomotives and power plants. The production department treats coal by power, resulting in three layers of coal that fluctuate within a range of 0.7-1.0 meters. My opinion is that resources evaluation and reserves calculation should be based on coking coal since the exploration of resources so as to maximize the utilization of coal resources reserves and extend the service life of mines. 2. Due to the rapid development of geophysical technology in recent years, especially the seismic method, all the parameters are input into the computer and processed quickly and with high accuracy. Therefore, it is suggested to change the exploration method of simply drilling in Ningxia, and adopt the geophysical methods to engage in comprehensive exploration. This can effectively reduce the drilling volume, shorten the exploration cycle and save investment. 3. “Coal Resources Exploration Regulations” provides medium-sized structure, the first level of advanced reserves ratio, large-scale mine is 60%, medium
