我国建国三十六年来,始终沿用苏联的原煤计量制度和方法。在建国初期,我国还没有完整的煤炭计量制度,当时煤炭洗选加工还不发达,洗煤比重还很小,原煤计量的弊病和问题不突出。随着洗选加工工业的不断发展,问题突出了。在原煤计量中还存在着各种各样的计量手段和方法,如以采煤掌子推进的进度来换算计量;小车或箕斗容积方式计量;皮带运输计量;水力采煤泵的流量和煤水比的换算计量;折算固定灰分计量,还有的直销手煤计量,大于50mm石
Thirty-six years since the founding of China, the Soviet Union has always followed the measurement of raw coal systems and methods. In the early days of the founding of New China, there was no complete system of coal measurement in our country. At that time, coal washing and processing was underdeveloped and the proportion of coal washing was still small. The disadvantages and problems of coal measurement were not prominent. With the continuous development of the washing and dressing industry, the problem has been highlighted. In the measurement of coal there are still a variety of measurement methods and methods, such as the progress of mining coal palm to measure the conversion; car or skip volume measurement; belt transport measurement; hydraulic coal pump flow and coal Conversion ratio of water measurement; Conversion of fixed ash measurement, there are direct coal metering, greater than 50mm stone
