pumpcrete

The test results showed that the pumpcrete pillar support is an ideal support measure for thin, flatlying or dip less than 30° orebodies.

试验结果表明，泵送混凝土人工点柱是水平及倾小于30°薄矿体开采理想支护手段。

Whereby providing the reliable basis of the dam cast and for corresponding temperature control measures during the overfall dam construction in high temperature with three level pumpcrete machines.

从温,大坝高温季节采用三级配混凝土泵浇筑溢流坝段可行性提供了可靠参考依据。
