Remote operation of continuous miners has enhanced the health and safety of underground miners in many respects; however, numerous fatal and non-fatal continuous miner struck-by accidents have occurred when using remote controls. In an effort to prevent these injuries, NIOSH researchers at Pittsburgh Research Laboratory examined the workplace relationships between continuous miner operators and various tramming modes of the equipment using motion captured data, predicted operator response times, and field- of- view data to determine causes of operator-machine struck-by events in a virtual mine environment. Factors studied included machine speed, direction of escape, operator facing orientation relative to the machine, work posture, distance from machine, and operator anthropometry. Close proximity to the machine, high machine tramming speeds, a right-facing orientation and operator positioning near the tail all resulted in high risk of being struck. It is hoped that this data will provide an improved rationale for operator positioning for remotely operated continuous miners.

The active development of robotics requires increasingly complex remote control devices. The remote control devices are increasingly large, complex, and expensive. They decrease economic efficiency of robotics and increase their price. The scientific task is the research into possibility of applying optical ministicks on the basis of light emitting diodes as the new type basic multifunctional controls of unified human­machine interfaces allowing us to control commonly known robotic equipment types using identical devices. During the research original ergonomic methods of purposeful combination of two ministicks on two actuating levers were used so that to provide convenience of tactile control of various robots without visual contact with controls. As a result of the research, new controls were created and patented. They became known as “polyjoysticks” (patent of Russian Federation No. 2497177) and allow controlling engineering facilities having up to 20 degrees of freedom which exceeds the similar parameters of known controls by factor of 3 to 5. Due to combined use of optical ministicks, two polyjoysticks and a video mask, a new generalpurpose generation humanmachine interface was created. It allows controlling various robots and vehicles, from tractor to aircraft. The discussion of the obtained results was carried out by comparing them with parameters of control panels of different robotics systems. The analysis of the comparison results has shown that the controls based on polyjoysticks and digital optical ministicks on the basis of light emitting diodes have the best indices in terms of implemented among known control devices, in terms of ratio of functionality to weight and volume of the devices. New interfaces have already been applied for developing multiagent robotic system control system for fire forest extinguishing.

Preliminary results are presented for a study to determine the feasibility of providing adequate human-engineered cabs in thin coal seams through the use of a remotely positioned operator. This study, which is being performed under contract to the U.S. Bureau of Mines, concentrates on the development of a cab for a continuous miner and involves three phases. First, workers were observed and questioned to produce a detailed task analysis of work performed by the miner operator and his helper, and a critical incidents analysis was conducted to define system requirements for handling unusual events in the work place. Second, evaluations were made of remote continuous mining system components in order to develop a baseline system configuration. Third, a baseline design concept was developed consisting of a remote, two-wheeled trailer cab linked to a Jeffrey 101 miner by coaxial cable. The miner is modified by adding to it an automatic cable handling system, a multiplexed remote control and sensor system, and two controllable closed circuit TV cameras. Potential safety and economic benefits are presented for the baseline concept.

NIOSH researchers have been examining underground coal mining activities in order to evaluate work crew hazards. In 1994 a continuous mining machine operator was killed by falling roof during extended cut mining. Many aspects of the incident were used by NIOSH researchers to develop a scenario interview. The goal was to provide a realistic framework for acquiring frank and detailed insights. The interview consists of two sections. The first describes the underground mining conditions. The second recounts the fatal incident. Each section is supplemented by a diagram and a set of questions addressing relevant safety issues. The interview was administered at three mines that actively take extended cuts. Researchers found the scenario approach to be an effective interview tool as well as an effective hazard awareness and safe work practices training platform.
