No matter the quality of coal, the size composition and water content as well, due to the bad environment of coal production and the vibration in the process of transportation, there always has some coal and other materials left which was very easy to cake on the bottom of the mine car after unloading. If we do not clean these remaining coal and rock meal soonly, they would be heavier and solider, which would increase the weight of mine car so that decrease the effective volume of it. Then it would not only affect the transportation ability of mine car directly and make the intense condition of the transportation system, but also increase the waste of electric power, and even make substantial difficulty in starting the spacial vehicle while transporting the electrical machinery truck. So cleaning the bottom of the mine car become espectially important.

不论煤质，粒度组成及含水量如何，由于煤矿生产环境的恶劣，加之在运输的过程中的振动等原因，卸车之后总会有少量的煤炭，煤矸等易粘结的物料粘结在矿车车箱底部及邻帮若不将这些残留煤，岩粉及时清除干净，则会越积越厚，越积越结识，增加了矿车自重，使矿车的有效容积减少，它不仅直接影响着矿车的运输能力，造成了运输系统的紧张状况，而且增加了电力资源的浪费，甚至使电机车运输是空列起动发生困难，所以清理车底的问题，在煤矿就显得尤为重要。

Abundant coal and other coal-derived particles were identified using organic spectrographic analysis.
