| 内容記述 | An analytical model for drilling process was proposed to describe the relations among physical properties of the rocks and mechanical data. Based on this model, a drilling system was developed. This drilling system can measure the mechanical drilling data and predict the geological conditions. 1) Development of the analytical model for rock drilling. In this analytical model, a drilling process is divided into continuous cycles, each of which includes two motions: feeding and cutting. Feeding is treated as an indentation motion. A linear relation exists between indentation pressure (thrust) and the indentation depth (penetration rate). Cutting forces and frictions of both the rake face and the flank face are examined. Especially, a virtual base is set to the model to simulate the contact surface between the flank face of the bit and the rock. Some relations among rock properties, bit shapes, and drilling parameters (rotary speed, thrust, torque, and stroke) were deduced. According to this model, drilling torque consists of four parts generated from cutting, friction, feeding, and idle running respectively. Similar to torque, specific energy also has four parts from cutting, friction, feeding, and idle running respectively. For this study, the effective specific energy is defined as the sum of specific energy consumed by cutting and feeding. It is more useful to evaluate uniaxial compressive strength (UCS) than other parameters are. 2) Development of the drilling system. The hardware of this system consists of a drilling machine (Trussmaster Series) and some instruments to measure mechanical data. The software can analyze the data from the mechanical data and predict the geostructure of roadways, rock physical properties and discontinuities of the strata. 3) Laboratory and field experiments. Some laboratory tests and field experiments were performed to verify the usefulness and effectiveness of the proposed model and the drilling system. With the mechanical data, the rock physical properties were evaluated. Meanwhile, the specimens taken from the fields were tested in laboratory to get their physical properties. The predicted values were agreed with the measured values. 4) Visualization of the geostructure. An application of VRML (virtual reality modeling language) was developed to display the predicted geostructure of roadway in 3D. The strata and the discontinuities (cracks, boundary faces, etc.) can be displayed. The results of this study show that the drilling system is useful and feasible. Our future work is to improve the prediction precision and to apply the drilling model to other types of drilling machines. | |||||||||||
