放矿计划图表放矿计划图表chart of ore drawingfong伙旧ng]lhuo tub旧。放矿计划图表(ehart of ore drawing)在崩落岩石覆盖下放矿时，根据选定的放矿制度和尽量提高矿块出矿强度等要求编制规定各漏斗放矿先后、时间和数量的计划图表。放矿计划图表应表明在什么时间、从哪些漏斗分别放出多少矿石和岩石。采用依次放矿的放矿制度时，可以根据物理模拟放矿结果编制放矿计划图表。因为在这种放矿制度中，从各个漏斗放矿的次序已经确定;在某一时间某一漏斗的一份放出中的矿石量和岩石量是多少，也能通过物理模拟放矿加以确定但用随机模拟放矿去编制该放矿计划图表、则更为准确。对用削高峰的放矿制度时，漏斗间放矿的顺序取决于高峰落在哪个漏斗上面物理模拟放矿过程中无法知道高峰落在哪个漏斗上面，靠估算则精度又太低;简易的办法是进行随机模拟放矿在随机模拟放矿中，按不断削高峰原则确定的各漏斗放矿的次序仍然是依次的，矿块的出矿强度太低为了提高矿块的出矿强度，应尽量增多同时放矿的漏斗.但应满足下列要求:(l)在同一条电耙巷道中不同时从两个以上的漏斗放矿，以免无法记录从每个漏斗放出量。(2)对于同时放矿的两个以上的漏斗，个漏斗放矿不应导致另外漏斗轴线上的崩落矿岩接触点下移.以保证崩落矿岩接触面尽量按要求下降。满足这两项要求的方法是，轮到从某漏斗放矿时，就把从该漏斗放矿的日期排在已排过的最后一天，然后看是否满足这两项要求。如果能满足，则往前挪一天;如果不能满足，则把这个日期排在最后一天的后面这样编制的放矿计划图表，就是放完该矿块的通盘计划图表。执行这种放矿计划图表时，还应逐日累计从每个漏斗放出的矿岩量，通过多退少补，使实际的累计量靠拢计划值(苏宏志)
