1. INTRODUCTION
Hello, my name is ________________. I work for NIOSH and we are doing a research study to get information on what coal miners think about the lighting on roof bolting machines. The interview takes about 8 minutes. Your participation is completely voluntary. You don't need to answer any questions you don't want to. Your responses to interview questions will be treated in a confidential manner, unless otherwise compelled by law. We do not record the names of the people we interview. The information you provide will be analyzed and reported along with the information provided by miners at other mines. In any public release of survey results, no data will be disclosed that could be used to identify specific individuals. Only NIOSH staff who are involved in collecting or preparing the information for analysis will have access to your answers.
Do you have any questions before I begin the interview?
2. BACKGROUND
To begin, I need to get some information about you and your experience in mining.
2.1 How many years have you worked as a coal miner?
□ < 2
□ 2 - 5
□ 6 - 10
□ 11 - 20
□ > 20
2.2 How many years have you worked with a roof bolter?
□ < 2
□ 2 - 5
□ 6 - 10
□ 11 - 20
□ > 20
2.2 What is the make and model of roof bolter that you currently use?
2.4 How old are you?
□ < 30
□ 30 - 39
□ 40 - 49
□ 50 and over
Public reporting burden of this collection of information is estimated to average 15 minutes or less per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to CDC/ATSDR Reports Clearance Officer, 1600 Clifton Road NE, MS D-74, Atlanta, Georgia 30333; ATTN: PRA (0920-XXXX).
2.5 What type of cap lamp do you use?
□ incandescent
□ LED with a corded battery pack
□ cordless LED
2.6 How long have you had this cap lamp?
□ < 3 months
□ 1 to 3 years
□ more than 3 years
3.0 ROOF BOLTER OPERATION
3.1 Overall, how would you rate glare when operating the roof bolter?
1 Unbearable
2 –
3 Disturbing
4 –
5 Just acceptable
6 –
7 Satisfactory
8 –
9 Just noticeable
3.2 Where and when is the glare the worst when operating the roof bolter?
3.3 Where and when do you need more illumination when operating the roof bolter?
3.4 Where and when do you need less illumination when operating the roof bolter?
3.5 Seeing floor hazards when operating the roof bolter is:
difficult easy
1 2 3 4 5
3.6 Seeing roof hazards when operating the roof bolter is:
difficult easy
1 2 3 4 5
3.7 Seeing rib hazards when operating the roof bolter is:
difficult easy
1 2 3 4 5
3.8 Can the roof bolter lighting be improved?
3.9 Do you think the extra lighting provided to illuminate the roof is helpful when performing bolting operations? Why or why not?
3.10 Do you think the extra roof lighting would make your job safer? Why or why not?
SPECIFIC QUESTIONS REGARDING DESIGN OF CONTROLS:
3.9 Do you look at your controls when you operate them? Y or N
3.10 Do the controls or directions of the controls ever come back after maintenance in the wrong place or the wrong direction? Y or N
3.11 Are you more likely to inadvertently pick the wrong control or pick the right control but move it in the wrong direction during your bolting cycle? Wrong Control Wrong Direction
3.12. Which controls do you inadvertently operate when you do make a control selection error?
3.13 Which control do you inadvertently move in the wrong direction when you do make a directional error?
Thank you for your time. This concludes this portion of our questions. We look forward to talking to you after you experience some of the changes to the roof bolting machine. We appreciate your feedback as it helps us to recommend designs that may help make your jobs easier and safer.
