[Abstract]:In order to study the technical index needed to be reached by road curing agent for truck transportation in opencast coal mine, the dust reduction and dust suppression in truck transportation link can be realized. In Shenharusu opencast coal mine, an experiment was carried out to monitor the specific pressure of the truck under two conditions of no load and full load. The main conclusion is that the maximum specific pressure to the ground of truck is 1.8 MPa, under the condition of full load. If the road surface strength is strengthened to achieve the truck dust suppression, the road surface strength needs to reach 1.8 MPa;. In the 0 ~ 5 cm depth of road surface, truck below 5 ~ 15 cm,15 cm depth of stationary layer under no-load has an effect on extreme attenuation, while at full load, the intensity of stationary layer depth of 5 ~ 20 cm, pavement should be up to 1.4 MPa.. It is necessary to construct a stable layer of 5 ~ 20 cm and a cemented layer of 0 ~ 5 cm on the road surface by curing agent, and both layers can achieve good curing effect and achieve the purpose of dust reduction and dust suppression in truck transportation link.
