A comparison of rock mass disturbance in TBM and drill and blast drivages at the Donkin Mine,Nova Scotia

Summary The initial phase of the Donkin-Morien project involves the driving of two parallel tunnels through an interbedded sequence of coal measures strata to intersect the Harbour Seam which lies approximately 3.5 km offshore. The No. 2 tunnel was driven a total distance of 3579 m using a 7.6 m diameter full face shielded Lovat TBM and supported by steel ring beams. The No. 3 tunnel was initially driven a distance of 1027 m using conventional drill and blast methods (7.6 m wide by 5.3 m high with a uniradial arch and supported by rock bolts and shotcrete). The TBM was subsequently used to complete the drivage of the No. 3 tunnel to the Harbour Seam.Both the No. 2 and No. 3 tunnels followed a thick sandstone unit at a grade of –20% for the first 900 m. This provided an opportunity to compare the rock mass disturbance resulting from two different excavation methods. A programme of field and laboratory measurements was therefore undertaken, which included: the use of a borehole dilatometer to determinein situ rock modulus,in situ gas permeability testing, seismic reflection surveys on the tunnel walls, and the laboratory testing of core samples.The paper examines the four different techniques used and compares the results obtained.

Computer-controlled automated jumbo drilling robot manipulator

Summary This programme involves the study of the technique of using a micro-computer to control a rock drilling machine. The motion of an existing jumbo machine has been successfully analysed. The kinematic control equations are established for any given geometrical configuration. The computer software has been written to demonstrate its feasibility. The needs of hardware implementation are also discussed.The Deputy Chief Engineer at Yangzhuang Coal Mine, Hueibei Coal Mining Bureau, China.     

The determination ofin situ rock thermal properties and the simulation of climate in an underground mine

Summary This paper describes the results from a continuing research project started in 1984, which is investigating improved methods for predicting the underground climate in hot mines. The Homestake Gold Mine in South Dakota was the site for testing methods, based on radial heat flow theory, to measurein situ values of the thermal conductivity and diffusivity of rock. The methods used proved to be quite within the capability of mine staff to carry out for themselves. The results were acceptable and verified thatin situ thermal rock properties can differ considerably from laboratory determined values, in this case by a factor of approximately two.A mine climate simulation program, CLIMSIM, was applied to case studies from the Homestake mine using the measured thermal rock parameters. The results showed good correlation between the measured and simulated values.

Optimization of the rate of return of the mine production process

Summary The basic foundations of an integrational method of modelling and estimating the economic effectiveness of a deep coal mine production process is presented. The method is founded on the concept of integration of smaller structural elements into larger ones in order to obtain a representational model of the whole mine production process. It involves analysis of the spatial, engineering and time structures of the mining process. The basic structural unit of the production process is the elementary time interval,T, together with a linear function of the approximate intensity of financial outlays or effects. The repeated integration of these elementary time intervals within the spatial, engineering and time structures of the mine production process can be extended to model the whole mine or discrete spatial structure elements.The model may be used to investigate the trends of financial outlays and effects, and their current values updated for arbitrarily assumed updating moments. The model can also be used as an investigation tool for analysing the economical effectiveness of the mine production process.     

Shaft design criteria

Summary Criteria for shaft design are described and methods of design developed. Among aspects covered in detail are: selection of shaft locations; shaft collar design and determination of collar dimensions; shaft lining design and estimation of side pressures; shaft insets and sump design. Factors considered, apart from geotechnical criteria include constraints imposed by surface structures, mineral handling and water flows.     

地下采动顺向缓倾构造山坡的滑移机理

采空区地表山体侧向变动,不同于一般天然山坡,也与采空区一般上覆岩层的变形破坏有异;它是二者复合机理的效应。本文在分析考察了毗邻电厂的横山顺倾构造山体、剖析了地下采空情况认为:山体侧向变动中,软弱夹层有决定性作用,变动范围、速率和规模与地下采空有关;并利用地质力学模型试验和数值模拟,探索了采动引起山体应力场及变动规律。结果表明,山体岩层的变形、位移、破坏、由直接顶板向地表发展,采空坍陷诱发了软弱夹层的蠕滑,则产生山体侧向滑移;电厂区地表隆起变形是山体侧向滑移挤压地基土的反映。通过现场实际调研、变形观测资料分析与数值模拟和模型试验的对比研究,提出了“坍落拱梁”的成生效应、挤压蠕滑效应、失稳效应;揭露了顺倾构造山体在采空影响下,具有地表、地下的“复合临空面”的“复合应力场”中“复合变动”的“复合机理”;并提出这种山体侧向变动机理的典型地质模式,借以论证山体稳定性。
