我们经过到现埸较长时间的观测和研究,并多次与矿有关方面交换意见,对应城石膏矿三分矿通风方案的确定作了合理的比较分析。现介绍如下: 一、概况应城石膏矿第三分矿,可采膏组为九组,膏层倾角为6～8°,走向东西,倾向南。井田范围:沿走向长为2500米(其中东翼部分为1500米,西翼部分为1000米),沿倾斜长为1100米。全矿分四个水平开采(自上至下,其中第十、九膏组为第一水平;第八、七膏组为第二水平;第五、四、三膏组为第三水平;第二、一膏组为第四水平)。目前只开采第二水平第七膏组。
After a long time of observation and research, we exchanged views with relevant parties on mine several times and made a reasonable comparative analysis on the determination of ventilation program for the third mine of gypsum mine. Now introduced as follows: First, the outline should be the third gypsum ore mine, recoverable paste group for the nine groups, cream layer angle of 6 ~ 8 °, to the east and west, south. Ida Range: It is 2,500 meters long (1,500 meters in the east part and 1,000 meters in the west part) along the length of 1,100 meters. The whole ore is mined in four levels (from top to bottom, of which the tenth and ninth plasters are the first level, the eighth and seventh plasters are the second level, the fifth, fourth and third plasters are the third level, Second, an ointment group for the fourth level). Currently only the second level of the seventh group of mining paste.
